Two parallel investigations were led by the Dutch, one into the technical cause of the crash, and a separate criminal inquiry. The technical report was released on 13 October 2015, and the criminal investigation reported some of their findings in September 2016.
On-site investigation In the hours following the crash, a meeting was convened of the
Trilateral Contact Group. After they had held a video conference with representatives of insurgents affiliated with the Donetsk People's Republic (who controlled the area where the aircraft crashed), the rebels promised to "provide safe access and security guarantees" to "the national investigation commission" by co-operating with Ukrainian authorities and OSCE (
Organization for Security and Co-operation in Europe) monitors. During the first two days of investigation, the militants prevented the OSCE and the workers of
Ukrainian Emergencies Ministry from freely working at the crash site.
Andrei Purgin, a leader of the Donetsk People's Republic, declared later that "we will guarantee the safety of international experts on the scene as soon as Kiev concludes a ceasefire agreement". By 18 July 2014, the
flight data recorder and the
cockpit voice recorder had been recovered by separatists, and three days later were handed over to Malaysian officials in
Donetsk. The voice recorder was damaged but there was no evidence that data had been tampered with. had by August 2014 delegated the investigation to the DSB because of the large number of Dutch passengers and the flight having originated in
Amsterdam. On 22 July 2014, a Malaysian team of 133 officials, search and recovery personnel, and forensics, technical and medical experts arrived in Ukraine. Approximately 200 special forces soldiers from Australia were also deployed to provide support for the JIT investigators. The United Kingdom sent six investigators from the
Air Accidents Investigation Branch (AAIB) and the UK
Foreign Office sent extra consular staff to Ukraine. It took until late July before the full international team could start working at the crash site, under the leadership of the
Dutch Ministry of Defence. On 30 July 2014, a Ukrainian representative said that pro-Russian rebels had mined approaches to the crash site and moved heavy artillery. On 6 August 2014, the experts left the crash site due to concerns about their safety. In mid-September they unsuccessfully attempted to regain access to the site. On 13 October 2014, a Dutch-Ukrainian team resumed recovery of victims' personal belongings. In mid-November 2014, work was undertaken to remove part of the wreckage from the crash site. Earlier efforts by the recovery team to salvage the MH17 wreckage had been frustrated by disagreements with the local rebels. The recovery operation took a week. The debris was transported to the Netherlands where investigators reconstructed parts of the aircraft. In August 2015, possible Buk missile launcher parts were found at the crash site by the Dutch-led
joint investigation team (JIT).
Cause of the crash launcher, similar to that used in the incident Soon after the crash, both American and Ukrainian officials said that a 9M38 series surface-to-air missile strike was the most likely cause. If so, then the missile was fired from a mobile Soviet-designed Buk missile system (
NATO reporting name: SA-11 "Gadfly"). At the time, Buk was the only surface-to-air missile system known to be deployed in the region that was capable of reaching the cruising altitude of commercial air traffic. Such systems, unless they receive information from larger networks, have limited capacity to distinguish between military and civilian aircraft. According to defence analyst Reed Foster (from
Jane's Information Group), the contour of the aluminium and the blistering of the paint around many of the holes on the aircraft fragments indicate that small, high-velocity
fragments entered the aircraft externally, a damage pattern indicative of a Buk. Ballistics specialist Stephan Fruhling of the
Australian National University's
Strategic and Defence Studies Centre concurred with this, explaining that since it struck the cockpit rather than an engine it was probably a radar-guided, rather than heat-seeking, missile equipped with a
proximity fuzed
warhead such as a Buk. Shortly after the crash,
Igor Girkin, leader of the Donbas separatists, was reported to have posted on social media network
VKontakte, taking credit for downing a Ukrainian An-26. The separatists later denied involvement, saying they did not have the equipment or training to hit a target at that altitude. Russian media also reported that
Alexander Borodai called one of the Moscow media managers 40 minutes after the crash, saying that "likely we shot down a civilian airliner". Witnesses in
Torez reported sightings on the day of the incident of what appeared to be a Buk missile launcher, and
AP journalists reported sightings of a Buk system in separatist controlled
Snizhne. He cited what he said were recorded conversations in which separatists expressed satisfaction to Russian intelligence agents that they had brought down an aircraft. One of the separatists acknowledged that the conversations had taken place, but denied that they were related to the crash of MH17 and blamed the Ukrainian government for shooting it down. According to Nayda, a Buk launcher used in the shoot-down was moved back into Russia the night after the attack. The head of the SBU,
Valentyn Nalyvaichenko, later claimed that rebels had intended to shoot down a Russian airliner in a
false flag operation to give Russia a pretext to invade Ukraine, but shot down MH17 by mistake. Journalists from the
Associated Press in Snizhne, Ukraine reported seeing a Buk M-1 enter the town operated by a man "with unfamiliar fatigues and a distinctive Russian accent" escorted by two civilian vehicles, which then moved off in the direction where the shoot-down later occurred. According to Ukrainian counterterrorism chief, Vitaly Nayda, after downing the airliner under separatist direction, the launcher's Russian crew quickly moved it back across the border into Russia. American intelligence agencies said that analysis of the launch plume and trajectory suggested the missile was fired from an area near Torez and Snizhne. Several other media outlets including
The Guardian,
The Washington Post and the
Sydney Morning Herald, reported that the aircraft was believed to have been downed by a rebel-fired missile. On 28 July 2014, Ukrainian security official Andriy Lysenko announced, at a press conference, that black box recorder analysis had revealed that the aircraft had been brought down by shrapnel that caused "massive explosive decompression." Dutch officials were reported to be "stunned" by what they saw as a "premature announcement" and said that they had not provided this information. On 8 September 2014, the
BBC released new material by
John Sweeney who cited three civilian witnesses from Donbas who saw the Buk launcher in the rebel-controlled territory on the day when MH17 crashed. Two witnesses said the crew of the launcher and a military vehicle escorting it spoke with
Moscow accents. On the same day Ignat Ostanin, a Russian journalist, published an analysis of photos and films of Buk units moving in Russia and Ukraine in the days before and after the MH17 crash. According to Ostanin, the markings on the specific launcher suspected of being used to shoot MH17, together with the number plates of the
large goods vehicle that carried the launcher, suggested that it belonged to the 53rd Anti-Aircraft Missile Brigade of the Air Defence Forces of the
Russian Ground Forces. On 8 October 2014, the president of the German
Federal Intelligence Service (BND) gave a presentation about MH17 to a German parliamentary committee overseeing intelligence activities. According to
Der Spiegel, the report contained a detailed analysis which concluded that pro-Russian separatists had used a captured Ukrainian Buk system to shoot down Flight MH17. The report also noted that "Russian claims the missile had been fired by Ukrainian soldiers and that a Ukrainian fighter jet had been flying close to the passenger jet were false". The
Attorney General of Germany opened an investigation against unknown persons due to a suspected
war crime. Between November 2014 and May 2016, UK-based investigative collective
Bellingcat made a series of claims, based on their examination of photos in social media and other open-source information. Bellingcat said that the launcher used to shoot down the aircraft was a Buk of the Russian
53rd Anti-Aircraft Missile Brigade based in
Kursk, which had been transported from
Donetsk to
Snizhne and was controlled by separatists in Ukraine on the day of the attack, and that the Buk launcher had a serial number 332. On 22 December 2014, the Dutch news service
RTL Nieuws published a statement from an unnamed local resident who said he had witnessed the shooting down of MH17, which he said was shot down by a missile from rebel territory. He had taken photographs which he had passed to the
SBU. In January 2015, a report produced by the German investigative team CORRECT!V concluded a Buk surface-to-air missile launcher operated by the
53rd Anti-Aircraft Missile Brigade shot down MH17. Other
circumstantial evidence was presented separately by various parties that supported this version, identifying specific launcher vehicle, operator name, truck transporting it and its alleged route through Russia and Ukraine. In March 2015, Reuters published statements from named witnesses from Chervonyi Zhovten (), close to Torez and Snizhne, who said they saw the Buk rocket passing over the village when it was fired from a field around 1.5 km away. It also published a statement from a witness who was said to be a separatist fighter (referred to by first name only) who confirmed that the launcher was placed in that area on the day of the Boeing crash to prevent Ukrainian airstrikes. In July 2015,
News Corp Australia published the transcript of a 17-minute video recorded at the scene shortly after the crash. The transcript and published segments of the video indicated that Russian-backed rebels arrived at the crash site expecting to find the wreckage of a military aircraft and crew who had parachuted from the aircraft. In May 2016,
Stratfor released satellite imagery taken five hours before the crash which showed a Russian Buk system travelling on a flatbed truck east through
Makiivka, 40 km away from Snizhne. Stratfor's concluded that a Buk system had moved from the Russian border toward Donetsk on 15 July 2014, and then moved back to the east on the afternoon of 17 July 2014, hours before Flight MH17 was shot down.
Dutch Safety Board reports Preliminary report On 9 September 2014, the preliminary report was released by the Dutch Safety Board (DSB). This preliminary report concluded that there was no evidence of any technical or operational failure in the aircraft or from the crew prior to the ending of the
CVR and FDR recordings at 13.20:03 hrs (UTC). The report also said that "damage observed on the forward fuselage and cockpit section of the aircraft appears to indicate that there were impacts from a large number of high-energy objects from outside the aircraft". According to the investigators, this damage probably led to a loss of structural integrity that caused an in-flight break-up first of the forward parts of the aircraft and then of the remainder with an expansive geographic spread of the aircraft's pieces.
Tjibbe Joustra, Chairman of the Dutch Safety Board, explained that the investigation thus far pointed "towards an external cause of the MH17 crash", but determining the exact cause required further investigation. They also said that they aimed to publish the final report within a year of the crash date.
Final report The Dutch Safety Board (DSB) issued its final report on the crash on 13 October 2015. The report concluded that the crash was caused by a Buk 9M38-series surface-to-air missile with a 9N314M
warhead. The warhead detonated outside and above the left-hand side of the cockpit. Fragments from the exploding warhead killed the three people in the cockpit and caused structural damage to the airliner leading to an in-flight break-up resulting in a wreckage area of and loss of the lives of all 298 occupants. The findings did not specify who launched the Buk missile, but the area identified by the DSB was controlled by pro-Russian separatists at the time of the downing, according to the final report. In addition to the technical investigation, the selection of the flight route was also investigated by the DSB. Some airlines had avoided eastern Ukrainian airspace prior to the MH17 shootdown, while many others, including 62 operators from 32 countries, had continued to fly routes over the region. The DSB judged that the Ukrainian authorities should have closed the airspace above eastern Ukraine prior to the incident due to the ongoing conflict and earlier military shootdowns, but noted that states involved in armed conflicts rarely did so. Investigators interviewed witnesses and examined forensic samples, satellite data, intercepted communications, and information on the Web. Participating in the investigation along with the Netherlands, are the four other members of the
joint investigation team (JIT), which joined in November 2014. Early in the investigation, the JIT eliminated accident, internal terrorist attack or air-to-air attack from another aircraft as the cause of the crash. In December 2014, in a letter to the
Security Council, the Netherlands'
United Nations representative wrote that "the Dutch government is deliberately refraining from any speculation or accusations regarding legal responsibility for the downing of MH17". Also in December, the assistant secretary of the
United States Department of State's European and Eurasian Affairs stated that the United States had given all of the information they held, including classified information, to the Dutch investigators and to the
International Civil Aviation Organization (ICAO). On 30 March 2015, the JIT released a Russian-language video calling for witnesses in the
Donetsk and
Luhansk regions who might have seen a Buk missile system. The video included some previously undisclosed recordings allegedly of tapped phone conversations between rebel fighters about the Buk. In one recording, of a conversation a few hours after the aircraft was shot down, a fighter says that a member of the Buk's accompanying crew had been left behind at a checkpoint. In another recording, dated the day after the shooting down, a rebel allegedly says the Buk system and its crew had been brought from Russia by "the Librarian". The video presented a "scenario" in which a Buk missile was transported on a
Volvo low loader truck from Sievernyi (), a town located within a kilometre of the Russian border (near
Krasnodon), to
Donetsk during the night of 16/17 July. In the week following the public appeal, the JIT received more than 300 responses resulting in dozens of "serious witnesses". In 2016, the presence of the
transloader of matching colour with a Buk missile was confirmed on a satellite photo of the area taken just a few hours before the downing of the airliner, which was described as "correlating with other evidence" by
Stratfor who found the photo in
DigitalGlobe archive. On 9 April 2015, Dutch authorities made available 569 documents concerning the shootdown. Personal information and official interviews had been redacted. A further 147 documents were not made public.
Findings of the joint investigation team On 28 September 2016, the JIT gave a press conference in which it concluded that the aircraft was shot down with a 9M38 Buk missile fired from a rebel-controlled field near Pervomaisky (Первомайський), a town south of
Snizhne. It also found the Buk missile system used had been transported from Russia into Ukraine on the day of the crash, and then back into Russia after the crash, with one missile less than it arrived with. The JIT said they had identified 100 people, witnesses as well as suspects, who were involved in the movement of the Buk launcher, though they had not yet identified a clear chain of command to assess culpability, which was a matter for ongoing investigation. The Dutch chief prosecutor said "the evidence must stand before a court" which would render final judgement. According to JIT head prosecutor Fred Westerbeke the criminal investigation is based on "immense body of evidence," including testimonies of live witnesses who saw the Buk launcher, primary radar data, original photos and videos. On 24 May 2018, after extensive comparative research, the JIT concluded that the Buk that shot down the flight came from the Russian
53rd Anti-Aircraft Missile Brigade in
Kursk. The head of the National Investigation Service of the Dutch police asked the eyewitnesses and insiders to share information about the identities of the Buk crew members, the instruction the crew members followed and persons responsible for the operational deployment of the involved Buk on 17 July 2014. The
Russian Ministry of Defence in turn stated that no Russian Buk crossed the border with Ukraine. Several other countries and international organisations expressed their support for the JIT's conclusions and the joint statement by the Netherlands and Australia. UK Foreign Secretary
Boris Johnson said the United Kingdom "fully supports Australia and the Netherlands," calling on Russia to cooperate. High Representative
Federica Mogherini of the EU stated that the European Union "calls on the Russian Federation to accept its responsibility" and to cooperate as well. The German government called on Russia to "fully explain the tragedy." The US Department of State issued a statement saying that the United States "strongly support the decisions by the Netherlands and Australia," requesting Russia to acknowledge its involvement and to "cease its callous disinformation campaign." NATO Secretary General
Jens Stoltenberg called on Russia to "accept responsibility and fully cooperate ... in line with
United Nations Security Council Resolution 2166." In response to the JIT's conclusions, Russian President
Vladimir Putin reiterated that the Russians are "not involved in it." Following release of the JIT report, Malaysian Prime Minister
Mahathir said the JIT was making Russia a "scapegoat" and that he did not believe the Russians whom the JIT had charged were involved. Conversely the Malaysian prosecutor supported the investigation by saying the findings "are based on extensive investigations and also legal research".
Proposed international tribunal In June 2015, the Netherlands, supported by the other JIT members, sought to create an international tribunal to prosecute those suspected of downing the Malaysian airliner, which would take up the case after the closing of the criminal investigation. The Dutch hoped that an international tribunal would induce Russian cooperation, which was considered critical. In late June 2015, the Russian government rejected a request by the five countries on the investigative committee to form a UN tribunal which would try those responsible for the shooting down of the aircraft, calling it "not timely and counterproductive." On 8 July 2015, Malaysia, a member of the
UN Security Council, distributed a draft resolution to establish such a tribunal. This resolution was jointly proposed by the five JIT member countries. Russian UN Ambassador
Vitaly Churkin responded, "I don't see any future for this resolution. Unfortunately, it seems that this is an attempt to organize a grandiose, political show, which only damages efforts to find the guilty parties." Russia later circulated a rival resolution which criticised the international investigation's lack of "due transparency" and demanded those responsible be brought to justice, but which did not call for a tribunal. In a vote, Malaysia's resolution gained majority support of the UNSC, but was
vetoed by Russia.
Criminal prosecution In a statement made on 5 July 2017 by the Dutch Minister of Foreign Affairs
Bert Koenders, it was announced that the JIT countries would prosecute any suspects identified in the downing of flight MH17 in the Netherlands and under Dutch law. A treaty between the Netherlands and Ukraine made it possible for the Netherlands to prosecute in the cases of all 298 victims, regardless of their nationality. This treaty was signed on 7 July 2017, and went into force on 28 August 2018. On 21 March 2018, the Dutch government sent legislation to the parliament, allowing the suspects involved to be prosecuted in the Netherlands under
Dutch law. On 19 June 2019, the
Dutch Public Prosecution Service charged four people with
murder in connection with the shooting down of the aircraft: three Russians,
Igor Girkin, Sergey Dubinsky, and Oleg Pulatov, and one Ukrainian, Leonid Kharchenko. International arrest warrants were issued in respect of each of the accused. One of the suspects, Lieutenant Colonel Oleg Pulatov, expressed his intention to join the legal process by being represented in court. Hearings in the trial began at the District Court of The Hague on 9 March 2020, with none of the accused in attendance. Igor Girkin gave an interview to journalist
Graham Phillips saying he would not attend the trial because he did not recognise the court's jurisdiction over Russian citizens. He said that he was not involved in the shoot-down, and that he considered the government of Ukraine to be responsible for the loss of life, because "only a moron or a criminal would send an airliner into a zone of active hostilities". In July 2019, SBU arrested Vladimir Tsemakh, head of air defence in DPR-controlled Snizhne during the attack on MH17.
Bellingcat described him as an important eye-witness to the events surrounding the downing of flight MH17. Bellingcat analysed his possible role and said that a video showed Tsemakh making "what appears to be a damning admission to his personal involvement in hiding the Buk missile launcher in the aftermath of its use on 17 July 2014". In August 2019, Russia reportedly added Tsemakh to its list in a previously agreed exchange of prisoners of war with Ukraine. In an article,
The Insider website commented on Russia's motives in requesting the exchange of a Ukrainian citizen. On 4 September 2019, an appeals court in Kyiv ruled to release Tsemakh. On 7 September 2019, Tsemakh was released during a Ukraine-Russia prisoner exchange. According to the
Dutch Foreign Minister Stef Blok, the exchange had been delayed for a week so that Tsemakh could be questioned by the Dutch Public Prosecution Service as a witness about the events surrounding the downing of flight MH17. Piet Ploeg, Chairman of the victims' relatives organisation "Stichting Vliegramp MH17", called Tsemakh's release "unacceptable". A number of witness statements, especially from the DPR armed forces, were presented anonymously due to fear of reprisal from Russia. The Dutch court, on considering defendant Oleg Pulatov's appeal against anonymous testimony, allowed twelve anonymous witness statements in the trial but barred the anonymous testimony of one witness. On 7 June 2021, the trial moved on to the evidence phase, during which lawyers and judges discussed their findings. Witnesses were called in to supply additional information. On 21 December 2021, the Prosecution recommended life sentences for four suspects accused of downing the plane. The trial reconvened on 7 March 2022, with the defence presenting oral arguments. On 17 November 2022, the court handed down
life sentences to three defendants, Igor Girkin, Sergey Dubinskiy and Leonid Kharchenko for the
murder of 298 passengers and crew. A fourth defendant, Oleg Pulatov, was acquitted on grounds of insufficient involvement in the incident. The presiding judge, Hendrik Steenhuis, said the court had concluded that MH17 was shot down by a Russian-made Buk missile launched from an agricultural field in eastern Ukraine, citing extensive evidence that did not leave "any possibility for reasonable doubt whatsoever" and that Russia had overall control of the separatist forces in eastern Ukraine when the plane was shot down.
European Court of Human Rights On 10 July 2020, the Dutch government announced that it intended to take Russia to the
European Court of Human Rights for "its role in the downing" of Flight MH17. By doing so, it said, it was "offering maximum support" to the individual cases already brought to the Court by the victims' families. On 25 January 2023, the ECHR ruled that it could adjudicate the case against Russia because evidence had established that the separatist militias were "under the jurisdiction of the Russian Federation" and that Moscow "had a significant influence on the separatists' military strategy". On 9 July 2025 the ECHR ruled that Russia was responsible for the downing of the plane and the deaths of everyone onboard. It further ruled that Russia had not performed any investigation, had not cooperated with the international investigation and had actively interfered with it, and it had not provided any legal remedy to the victims.
Convention on aviation legal action On 14 March 2022, Australia and the Netherlands announced that they had launched a joint legal action against Russia under Article 84 of the
Convention on International Civil Aviation. On 12 May 2025, the
International Civil Aviation Organization (ICAO) council ruled that Russia was in breach of the Chicago convention and responsible for downing MH17. == British ISC report ==
