Earlier, the United States military's Central Command spokesman Colonel John Thomas said the U.S. strike at Shayrat airfield near Homs in central Syria had destroyed more than 20 Syrian jets. "If he needs to do more, he will". Those include getting rid of Syrian President Bashar al-Assad's remaining chemical weapons stocks and pressing Assad to negotiate Syria's future.
"There's not any sort of option where a political solution is going to happen with Assad at the head of the regime", Haley told "State of the Union" anchor Jake Tapper.
"You can't imagine a stable and peaceful Syria with Assad in charge", said Spicer. But he did say this the day before: "I do change and I am flexible". In the circumstances the Foreign Secretary's decision to postpone any Moscow visit whilst working to secure G7 support for US Secretary of State [Rex] Tillerson's mission to Moscow seems a sensible judgement. "It's important that we keep our priorities straight", Tillerson told CBS's "Face the Nation".
Republican Senator Rand Paul also tweeted his opposition, writing "While we all condemn the atrocities in Syria, the United States was not attacked". "We are prepared to do more".
Trump's ambassador to the United Nations, Nikki Haley, said the United States was willing to take more action against Assad, while White House officials cautioned that the strikes did not signal a broader shift in USA policy.
Last week's nerve gas attack in the rebel-held town of Khan Sheikhoun, which killed more than 80 people, stirred President Donald Trump to strike for the first time at Assad's forces.
Barazi did not offer further details, and the U.S. Defense Department referred questions about conditions at the air base to the Damascus government.
The Syrian Observatory for Human Rights said it was unclear if the strike on the rebel-held town in northwest Syria's Idlib province was carried out by Syrian planes or those of government ally Russian Federation.
It was not clear whether planes from Shayrat participated in strikes Saturday that killed at least 18 civilians near the small city of Sheikhoun.
A U.S. air strike in response to a suspected chemical attack damaged or destroyed 20% of Syria's operational aircraft, the United States has said. Russian Federation says that a conventional airstrike hit a rebel depot containing "toxic substances".
"The Russian failure to deliver the 2013 deal would make them either complicit or betrayed by their Syrian ally".
And one of Trump's most positive (if not controversial) worldwide relationships now seems frayed: the Kremlin immediately condemned the strikes.
Trump also suggested on Twitter that the USA wasn't specifically trying to hit runways at the airfield during the operation. He did not elaborate, other than to note that runways are easily and quickly repaired.

While Trump repeatedly dismissed the allegations of Russian involvement as "fake news", the FBI and House and Senate intelligence committees have open investigations into the matter.
Idlib province is largely held by an alliance of rebels, including a former Al-Qaeda affiliate, and is regularly targeted in Syrian and Russian air strikes.
The American strikes "aim at slowing the victories of the Syrian army and its allies, and reinforcing terrorist groups", they said in a statement.
While US and Russian pilots can use radar to see each other, the lack of a direct line of communication would further heighten the risks of misunderstandings or accidents in Syria's already crowded skies.
