International law The
United Nations Charter requires a mandate from the
United Nations Security Council for sovereign states to use force for the purpose of maintaining international security, but not for acting in self-defence or the protection of populations threatened by extermination at the hands of their own government. Since the UN Charter came into effect in 1945, military action in retaliation or
reprisal to the act of another state has been prohibited; but a reprisal may be justified if its aim is to force the other state into compliance with its international obligations. Russia's use of its
veto meant there was no prospect of the Security Council authorizing the use of force. Therefore, military action relies on an international public order argument based on defending the credibility of the prohibition of the use of chemical weapons, enforcing Syria's obligations under the terms of its membership of the
Chemical Weapons Convention, and protecting civilians from further chemical weapon attacks to alleviate humanitarian suffering. The strikes came hours before inspectors from the
OPCW Fact-Finding Mission were due to arrive in Syria to investigate the attack. The United Kingdom published its legal position regarding military action which concluded limited strikes are justified on humanitarian grounds. After the strikes, the
UK Parliament debated the considerations under international law regarding the urgency of the intervention, and whether there was a lack of practical alternatives.
Forces involved and Chairman of the
Joint Chiefs of Staff Joseph Dunford briefing reporters on the attack preparing to launch a strike mission from Al Udeid Air Base The strikes were carried out by the forces of the United States, the United Kingdom, and France and were delivered by ship-launched, submarine-launched and airborne
cruise missiles. All of the missiles launched by British and French forces were either
Storm Shadow (SCALP EG) missiles, or
Missile de Croisière Naval (MdCN for Naval Cruise Missile) sea-launched cruise missiles in French service. Flying from
RAF Akrotiri in
Cyprus, four
Royal Air Force Tornado GR4 fighters of
No. 31 Squadron, supported by four
Eurofighter Typhoon air superiority fighters of
No. 6 Squadron, fired a total of eight Storm Shadow missiles. The
Royal Navy deployed the
Type 45 destroyer, , to provide air defense for allied naval forces. The French Navy deployed a strike group in the Eastern Mediterranean consisting of the , the , the , and the
FREMM multipurpose frigates , , and ; the latter ship fired three MdCN land attack missiles. The French strike group was accompanied by the
US Navy , which launched six Tomahawk cruise missiles. The
French Air Force participation in the strikes consisted of five
Rafale B fighters from the
Escadron de Chasse 1/4 Gascogne based at
Saint-Dizier Air Base, each carrying two SCALP EG missiles, four
Mirage 2000-5F air superiority fighters from the
Escadron de chasse 1/2 Cigognes from
Luxeuil Air Base, two
E-3F airborne early warning and control planes from the
36e Escadre de commandement et de conduite aéroportée Berry from
Avord Air Base, and six
C-135FR tankers from the
Groupe de ravitaillement en vol 2/91 Bretagne from
Istres Air Base. US forces included two
US Air Force B-1B Lancer bombers from the
34th Bomb Squadron, which fired a total of nineteen
JASSM missiles after taking off from
Al Udeid Air Base in
Qatar. They were accompanied by four
F-22A Raptor air superiority fighters from the
95th Fighter Squadron, two
KC-10 Extender tankers from the
908th Expeditionary Air Refueling Squadron and one
US Marine Corps EA-6B Prowler electronic-warfare aircraft from
VMAQ-2, which all departed from
Al Dhafra Air Base in the
United Arab Emirates. Immediately after the strike it was claimed that long-range
JASSM-ER had been fired by the two B-1B Lancer bombers, but five days later, the U.S. Air Force Central Command issued a correction saying that actually older JASSM-A were used. From a position in the
Red Sea the US Navy fired seven and the thirty Tomahawk cruise missiles, while the
Arleigh Burke-class destroyer fired twenty-three Tomahawks from a position in the northern part of the
Persian Gulf. The
Arleigh Burke-class destroyer, was reported to have participated in order to mislead defending forces, firing no missiles. US Secretary of Defense
Jim Mattis said twice as many weapons were used in the strike as in the
2017 Shayrat missile strike; an anonymous US Defense Department official quoted by
The Washington Post said about 100 Tomahawk missiles were fired by the US. According to US military's
Director of the Joint Staff, the allocation of missiles to targets was: •
Barzah scientific research centre (Damascus): 57 Tomahawk and 19 JASSM missiles. •
Him Shanshar military installation storage site (west of Homs): 9 Tomahawk, 8 Storm Shadow, 3 MdCN, and 2 SCALP missiles. • Him Shanshar military installation bunker: 7 SCALP missiles. Syria responded using its air defense systems, and its state media aired a video purporting to show a successful missile interception. The Syrian state news agency SANA and Colonel-General Sergei Rudskoi of the Russian military said Syria used Russian and Soviet air defense systems
Pantsir-S1,
S-125,
S-200,
Buk, and
Kvadrat.
Strikes , Syria President
Donald Trump announced the strikes at 9 pm
EDT, 13 April (4 AM, 14 April in Syria, 2 AM in London, 3 AM in Paris) along with allies France and the United Kingdom. Explosions were heard in Damascus, the capital of Syria, just as Trump was speaking. he was contradicted by other American and French officials. US
Chairman of the Joint Chiefs of Staff Joseph Dunford said three sites were targeted: a
scientific research center in
Damascus, a
chemical weapons storage facility west of
Homs, and an equipment storage facility and command post also near Homs. The UK
Ministry of Defence reported British aircraft struck the
Him Shanshar chemical weapons precursor storage site 15 miles west of
Homs. Witnesses reported loud explosions and smoke in the capital Damascus in the early morning, including in the
Barzeh neighborhood, the site of the
Barzah scientific research centre, a major research establishment. The
Syrian Observatory for Human Rights (SOHR) said the attack sites included a scientific research center in Damascus and another in the Homs area, as well as military bases in Damascus and Homs. Similarly, France said none of the twelve missiles it fired appear to have been intercepted, although there were reports that between three and seven French missiles were not fired due to malfunctions. The Syrian Army said it "intercepted most of the missiles", The SOHR, which is cited by many western media organisations, reported no known casualties, but stated there was considerable material damage while also saying that the
Syrian Air Defense Force intercepted and downed at least 65 missiles. Syria's state-run TV news reported three civilians injured at Homs, and that the missile strike there was "aborted". == Aftermath ==
