This frame grab from video provided by the government-controlled Syrian Central Military Media, shows missile flying over the capital Damascus during airstrikes by the United States, France and Britain, in Syria, Saturday, April 14, 2018.
Marine Lieutenant General Kenneth McKenzie, director of the Joint Staff, rejected assertions from Russian Federation and Syria that scores of the Western missiles were shot down.
Although the operation was secretly unfolding for hours before the first impact, it only took minutes from the first to the last detonation from 105 precision-guided missile strikes on three Syrian chemical weapons targets, officials said. He said Syria's air defenses were ineffective and that numerous more than 40 surface-to-air missiles fired by the Syrians were launched after the allied attack was over.
President Donald Trump declared "mission accomplished" in Friday night's strike on three Syria targets and argued that it "could not have had a better result".
"Before the attack took place last night, North Atlantic Treaty Organisation allies exhausted all other possible ways to address this issue to the U.N. Security Council but. were blocked by Russian Federation. Mission Accomplished!", Trump tweeted Saturday.
The Pentagon said Saturday that a joint US-British-French operation against Syria's regime had "successfully hit every target", countering assertions from Russian Federation that dozens of missiles were intercepted.
"It's intolerable for a civilized nation to use chemical weapons", Pentagon spokeswoman Dana White said Saturday.
In 2013, Syrian agreed to relinquish its chemical weapons following an attack - also in Duoma - which killed hundreds of people.
The strikes, more limited than once seemed likely, were created to deter the Assad regime's use of chemical weapons once and for all.
"Such attacks will not deter our armed forces and allied forces from persisting to crush what is left of the armed terrorist groups", the military said.
"There's still a residual element of the Syrian program that's out there", he said. France released a report which said that Damascus was to blame for the poison gas attack on Douma, the last holdout for anti-Assad rebels near Damascus.
Defense Minister Itsunori Onodera said the situation in Syria "is worrying to the worldwide community, including Russian Federation".
At a Pentagon briefing, Dunford said "this wave of airstrikes is over", but defense officials added they are prepared for a sustained campaign until the Syrian regime ceases its alleged use of chemical weapons.
Mattis, however, said the assault was a "one-time shot", so long as Assad does not repeat his use of chemical weapons. "We can not tolerate the normalization of the use of chemical weapons, which is a direct threat to the security of the Syrian people and our collective security".
The United States allies in the attacks are France and Britain.
- Syrian state TV called the attacks a "blatant violation of global law and shows contempt for worldwide legitimacy". He called on Moscow to change course and join the West in seeking a more responsible regime in Damascus.
Mrs May said "it was right we acted the way that we did" for operational security reasons to help protect the military.
The U.S. military, along with the United Kingdom and France, conducted a "proportional, precision, coordinated" strike in response to the Syrian regime's use of chemical weapons.
Paris and its allies warned Russian Federation beforehand because they wanted to avoid any escalation of the Syrian conflict, Parly said.
Among the initial targets according to accounts from inside Syria were a branch of a research centre that has been linked to suspected chemical weapons development, several air bases and the headquarters of some of the Syrian army's elite units.
