The Trump Administration has signaled that it intends to keep the military heat on Syrian President Bashar Assad - even as Turkish officials urged the U.S.to ramp up its efforts.
Turkish President Recep Tayyip Erdogan on Friday welcomed the U.S. strike on an airbase of the Syrian regime but said it was not enough and more action was needed.
U.S. President Donald Trump ordered the strikes after he blamed Assad for this week's chemical attack, which killed at least 70 people, many of them children, in the Syrian town of Khan Sheikhoun.
"I find it disappointing, but sadly, not that surprising".
Erdogan described the strike on a Syrian airfield in Shayrat, Homs province, as "a positive and concrete step" against the alleged "war crimes of the Assad regime", as cited by Reuters. "The U.S. strike is one-off and limited", said Aaron Stein, a senior fellow at the Atlantic Council think-tank.
Johnson says Tillerson will be able to give a "clear and coordinated message to the Russians".
Trump, Xi meet again - in shadow of missile strikes on Syria
Traveling with Trump are first lady Melania Trump, Treasury secretary Steve Mnuchin, Commerce secretary Wilbur L. A senior White House official said Pyongyang would be a key test for the Trump-Xi relationship.
But it highlights the rudderless nature of Turkish policy in Syria, as Ankara tries to forge stronger relations with both Moscow, Assad's main backer, and Washington, a North Atlantic Treaty Organisation ally hitherto reluctant to confront the Syrian leader head-on.
Special equipment to collect samples for further scientific analysis should be used at the airfield, the defense ministry said, adding that Russian Federation has already undertaken similar procedures in Aleppo, Syria where it said chemical weapons had been used by militants.
Saudi Arabia says the missile launch by Trump was the right response to "the crimes of this regime to its people in light of the failure of the worldwide community to stop it". "The destruction of the Sharyat airbase marks an important step to ensure that both chemical and conventional attacks against the civilian population do not go unpunished", he added.
Other than that, he added, "there is no change to our military posture" toward Syria. But it remains to be seen what that role would be.
"My priority is now to continue contact with the USA and others in the run-up to the G7 meeting on 10-11 April - to build coordinated worldwide support for a ceasefire on the ground and an intensified political process", Johnson said.
"Turkey is where it was on April 6, 2017".
