U.S. Secretary of State Rex Tillerson said in an interview with ABC's This Week program aired on April 9 that in meetings next week in Moscow, he will call upon the Russian government to live up to a 2013 agreement that was meant to strip Syria of its chemical-weapons stockpiles.
The chemical weapons attack in Syria that triggered retaliatory American airstrikes hasn't shifted USA priorities toward ousting Syrian President Bashar Assad, top Trump administration officials said.
The chemical attack on Khan Sheikhoun on Tuesday triggered a USA missile attack two days later that struck a Syrian airbase in central Syria killing nine people.
"If he needs to do more, he will do more", Haley said when asked if Trump would order more strikes.
US Secretary of State Tillerson is due to arrive in Moscow on Tuesday for two days of talks. US officials said they feel confident Syrian President Bashar Assad's government was responsible.
A senior military source in the alliance fighting in support of President Bashar al-Assad said the airbase had been mostly evacuated thanks to a warning from Russian Federation, which has deployed its military to Syria in support of Assad.
But Sir Michael said the launching of nearly 60 missiles at the regime airbase from which the attack is said to have originated would now make future incidents less likely.
Syria: What led to the United States air strikes?
There's no evidence that chemical weapons were stockpiled at the Shayrat airfield targeted by the strike, Russian Defense Ministry spokesman Igor Konashenkov said in an emailed statement.
Standing firm, the Trump administration signaled new sanctions would soon follow the missile attack, and the Pentagon was even probing whether Russian Federation itself was involved in the chemical weapons assault that compelled President Donald Trump to action.
According to Haley, the Assad regime has committed atrocities on innocent Syrian civilians multiple times.
At least 70 civilians were killed in the chemical attack on the region of Khan Sheikhoun.
It said the woman killed had fled to the town from her hometown of Latameh in central Syria.
Still, most Republican leaders applauded the president, and some Democrats backed him, too.
Russian Federation and Iran have backed Assad in Syria's six-year-long conflict, as has the Shia militia Hezbollah.
The defence secretary said Syria needed a government in which Mr Assad played no part. "Secondly, we don't see a peaceful Syria with Assad in there". "And just to simply say, you know, 'the president put up a red line and then didn't act" is really insufficient in terms of making policy", Richard Stengel, former undersecretary of state for public diplomacy, said on MSNBC's "Morning Joe".
