All NATO member states expressed their support for the strikes of France, the United Kingdom, and the United States against Syria, NATO Secretary General Jens Stoltenberg said on Saturday.
Meanwhile, UN Secretary-General Antonio Guterres has urged the members of the organisation to show moderation in the prevailing "dangerous" climate and to respect worldwide law.
"I call on the members of the Security Council to unite and exercise that responsibility", Guterres said.
President of the European Council Donald Tusk also supported the joint strikes. "But at the same time, I think it really will be unsafe if the worldwide community accepts use of chemical weapons and therefore we support the actions taken last night", Stoltenberg told reporters, when asked if the military operation in Syria might threaten the UN-led search of the political solution of the conflict in the Middle Eastern country.
Ahead of an impartial investigation by the Organization for the Prohibition of Chemical Weapons, the United States, Britain and France joined the chorus, accusing the Bashar al-Assad government of using chemical weapons.
"The three Allies stressed that a significant body of information indicated that the Syrian regime was responsible for the horrendous attack against civilians in Douma on 7 April, which killed a large number of children, women and men". Israel did not deny or confirm any responsibility.
