Asked about Trump's "Mission Accomplished" assertion, White said it pointed to the successful targeting of three Syrian chemical weapons sites. "I'd use three words to describe this operation: precise, overwhelming and effective".
The Pentagon said a barrage of more than 40 Syrian surface-to-air missiles had "no material effect" on the allied attack, which McKenzie said struck their targets. But there was a second, unspoken message: The incoming cruise missiles did not cross the threshold that would provoke a military response against Western forces.
The prime target of the operation was the Barza Research and Development Center in the greater Damascus area, which McKenzie noted was "one of the most heavily defended aerospace areas in the world".
In the attack Friday night, Britain and France joined USA forces to hit three targets instead of last year's one and with 105 missiles, almost double the number last year.
Mrs May drew a link with the nerve agent attack on former Russian spy Sergei Skripal and his daughter Yulia in Salisbury, telling a news conference: We can not allow the use of chemical weapons to become normalised - either within Syria, on the streets of the United Kingdom or elsewhere.
North Atlantic Treaty Organisation representatives planned a special session to hear from U.S., British and French officials.
But a United States official familiar with the military planning said there could be more air strikes if the intelligence indicates that Assad has not stopped manufacturing, importing, storing or using chemical weapons, including weaponised chlorine. While the Russians continue to support these heinous war crimes, the Syrian regime continues to violate its obligations under the Chemical Weapons Convention and the UN's Organization for the Prohibition of Chemical Weapons.
Syrian television called the attacks a "flagrant violation" of global law, and Irans supreme leader, Ayatollah Ali Khamenei, derided them as a "military crime".
In his nationally televised speech Friday night, Trump told Americans that the US had to respond.
Russian Federation should take airstrikes on Syria as a warning over its use of chemical weapons, Theresa May has said.
German Chancellor Angela Merkel said the West's response was "necessary and appropriate".
Stoltenberg also faulted Russian Federation, which he said was aiding Bashar al-Assad and had allowed his forces to operate in the area where the most recent chemical attack occurred. Bolton has often justified US military involvement in distant countries.
"This is hard to do in a situation like this", he said, in light of the volatility of chemical agents.
But she also drew a link with the nerve agent attack on Russian former spy Sergei Skripal and his daughter Yulia in Salisbury. But the description from an ally put things differently.
"We have sought to use every possible diplomatic channel to achieve this", the prime minister said.
Colombian President Juan Manuel Santos voiced support for the attacks, while condemning the use of chemical weapons.
"Russia vows to shoot down any and all missiles fired at Syria".
The Syrian government has repeatedly denied any use of banned weapons.
Just ten days before launching the retaliatory strike, Trump had stressed his impatience to bring USA troops home from Syria, where they've been battling ISIS.
A year later, the joint OPCW-U.N. panel determined the Syrian government had twice used helicopters to deploy chlorine against its opponents in civilian areas in northern Idlib province.
Syria and Russian Federation have denied any involvement in the alleged attack, and Syria has repeatedly denied using chemical weapons.

"This is how you want worldwide affairs to be conducted now?" said Nebenzia, according to a translation of his comments in Russian.
The demonstrations in support of Bashar Assad were carried live on state TV, which also reported that regime air defenses had intercepted most of the missiles fired by the United States, Britain and France to punish Syria's purported use of chemical weapons.
