Russian allegations of Ukrainian and Western involvement Putin and the FSB suggested that Ukraine was involved in the attack, without offering evidence. Russia and Ukraine have been
at war since 2014 and Russia has been undertaking
a full-scale invasion of the country since 2022.
Nikolay Patrushev, the secretary of the
Security Council of Russia, claimed that Ukraine was behind the attack.
Alexander Bortnikov, the head of the FSB, said that "radical Islamists" prepared the attack with help from Ukrainian and Western "special services".
Maria Zakharova of the
Russian foreign ministry accused the US of using Islamic State as a "
bogeyman" to cover for Ukraine. On 5 April, it also announced that it had found images of
Ukrainian flags and a Ukrainian postage stamp from a phone belonging to one of the suspects. Latvia-based Russian news outlet
Meduza reported that
state media in Russia were instructed by the Russian government to highlight possible "traces" of Ukrainian involvement. A day after the attack, pro-Kremlin Russian television station
NTV broadcast an
audio deepfake purporting to confirm Ukrainian involvement. On 26 March, Putin's claims were seemingly contradicted by his close ally, Belarusian president
Alexander Lukashenko, who said the attackers had first tried to cross into Belarus. Ukraine denied any involvement in the attack, and described the FSB's claims as "very doubtful and primitive"
disinformation, noting that the border is heavily militarized on both sides, guarded by soldiers and drones,
mined in many areas, and often shelled from both sides. Ukraine's
Foreign Ministry rejected the Russian allegations, calling them a "planned provocation by the Kremlin to further fuel
anti-Ukrainian hysteria in Russian society, create conditions for increased
mobilisation of Russian citizens to participate in the criminal aggression against our country, and discredit Ukraine in the eyes of the international community." The ministry also implied that the attack was a
false flag operation by the Russian government. Ukraine's
Defense Intelligence also said the attack was a "deliberate provocation by the Russian special services" at the behest of Putin. On 23 March, Ukrainian President
Volodymyr Zelenskyy said that Putin, "instead of dealing with his citizens of Russia, addressing them...remained silent for a day – thinking how to bring this to Ukraine." On 25 March, Zelenskyy called Putin's claims "sick and cynical". while UK
Chancellor of the Exchequer Jeremy Hunt called the Russian allegations "a smokescreen of propaganda to defend an utterly evil invasion of Ukraine." The Ukrainian-based militant groups
Russian Volunteer Corps and
Freedom of Russia Legion also denied involvement. Putin, who previously said the attack was caused by "radical Islamists" aided by the U.S. and Ukraine, later said that the act was not one of Islamic terrorism, as it demonstrated "a unique example of interfaith and interethnic unity". On 6 April, the
Tajikistani foreign ministry denied claims by Russian officials that Ukraine was recruiting mercenaries in the country through its embassy in
Dushanbe.
Domestic Putin wished those injured in the attack a speedy recovery and praised the doctors involved in treating the victims. Prime Minister
Mikhail Mishustin said that "the perpetrators will be punished. They do not deserve mercy."
Ministry of Foreign Affairs spokesperson
Maria Zakharova called for the
international community to condemn the attack, which she called "a monstrous crime". as did
Yulia Navalnaya, the widow of opposition figure
Alexei Navalny, who
died five weeks before the attack. Navalny associate
Ivan Zhdanov criticised Russian security services for their "catastrophic incompetence" and the FSB for being "busy with everything except its direct responsibilities – killing their political opponents, spying on citizens and prosecuting people who are against the war." Another associate,
Leonid Volkov, said that the FSB "can't do the only job it really should be doing: preventing a real, nightmarish terrorist attack." Exiled oligarch and Putin critic
Mikhail Khodorkovsky said the attack showed the "impotence" of the Kremlin's security apparatus.
Novaya Gazeta Europes chief editor,
Kirill Martynov, criticized Putin for dismissing Western intelligence warnings and focusing resources on "
LGBT extremists" and the war with Ukraine instead of guarding against "real threats".
Tatyana Moskalkova, Russia's
Commissioner for Human Rights, also said that it was "absolutely inadmissible to use torture against detainees and accused persons", and reiterated that "any procedural operational actions must be carried out in accordance with the law". Senior members of
United Russia called for the return of the
death penalty in Russia. In late March 2024, more than 50% of Russians believed that Ukraine was responsible for the terrorist attack, while 27% said
Islamic State was responsible and 6% blamed the so-called "
collective West", according to a survey conducted by OpenMinds. The Islamic State was blamed most often by young people aged 18-30 who opposed the war in Ukraine. On 3 April, Russia's
Defense Ministry announced that "around 16,000 citizens" had signed military contracts in the last 10 days to fight as contract soldiers in the
Russo-Ukrainian War, with most of them saying they were motivated to "avenge those killed" in the Crocus City Hall attack.
International The United States embassy in Moscow expressed "sincere condolences to the Russian people", while advising its citizens to avoid the area as they were "severely limited" in their ability to assist US citizens due to the limits placed on US personnel's ability to travel within Russia. The
British embassy in Moscow condemned the attack and expressed its "sincere condolences to the relatives and loved ones of those hurt and killed in today's events." In IS–KP stronghold Afghanistan, where the ruling
Taliban were
attacked by IS–KP just a day earlier, the
Ministry of Foreign Affairs called the attack in Russia "a blatant violation of all human standards" and called on neighboring countries to cooperate "against such incidents directed at regional destabilization". Numerous countries' governments condemned the attack and expressed their condolences to the Russian people and families of the victims. In many nations, including
Armenia,
Azerbaijan, and
Kazakhstan, flowers were laid outside Russian embassies in memory of the victims of the attack. Tajikistan also warned against "fake information" about the alleged role of Tajik citizens in the attack.
United Nations Secretary-General António Guterres, the European Union, the
North Atlantic Treaty Organization, and
Moussa Faki, the
Chairperson of the African Union Commission also condemned the attack and expressed condolences.
Pope Francis also expressed condolences to the victims and families. The attack was also condemned by
Hezbollah and
Hamas. On 30 March, foreign diplomats from the United States, European Union, Africa, Latin America, and representatives of the United Nations and other organizations attended a ceremony to lay flowers at the memorial near Crocus City Hall.
French terror alert level On 24 March, the French government raised its security alert to its highest level, with Prime Minister
Gabriel Attal citing the Crocus City Hall attack as one of the reasons. Following a phone call between French defence minister
Sébastien Lecornu and his Russian counterpart
Sergei Shoigu on 3 April in which the latter suggested French collusion with Ukraine in the attack, president
Emmanuel Macron dismissed the accusations as "ridiculous" and "indeed baroque and threatening."
Crackdown on IS in Turkey Since the attack, the Turkish government has expanded its crackdown on IS by detaining over 180 people suspected to have links to the group. This includes 147 detained on 26 March in raids across 30 provinces. According to the Turkish administration's
Minister of the Interior,
Ali Yerlikaya, the country as of March 2024 carried out a total of 1,316 counterterrorism operations against IS since June 2023.
Reciprocal visa requirements On 8 April, Turkey announced that it had cancelled a 2018 bilateral visa-exemption agreement with
Tajikistan citing "security concerns" and that Tajik citizens will need to
obtain a visa before traveling to Turkey. The visa requirements went into effect on 20 April. On 16 April, the Tajik government announced that it would be
imposing visa requirements on Turkish citizens visiting the country, citing the "principle of reciprocity" and claimed the rule change is a response to Turkish government measures on imposing a visa regime on Tajiks. It has also advised its citizens visiting Turkey to "take necessary precautions" while those using Turkey as a transit route are encouraged to explore alternative travel routes. == Monument ==
