The airstrikes on the opposition-held northern town of Khan Sheikhoun, where 87 people were killed in the chemical attack earlier this week, killed a woman and wounded her son, according to the Britain-based Syrian Observatory for Human Rights and the Local Coordination Committees, an activist collective.
Even before Thursday's strikes, the absence of a coherent USA strategy toward the Middle East was already worrying many in Congress and in foreign capitals.
Shortly after laughing with China's Xi Pingping, Xi's wife Peng Liyuan and First Lady Melania in the ornate Mar-a-Lago dining room, US President Donald Trump made a televised address in front of a hastily assembled backdrop to say he had ordered a surprise strike on a Syrian airfield.
"No child of God should ever suffer such horror", Trump told reporters after his strike.
"What America waged in an aggression on Syria is a crossing of red lines".
The move appeared politically astute.
It also offered a window into the decision-making style of the new President, even if the exact reason for such an abrupt about-face remained unclear.
Johnson expressed his support to the United States for Friday's missile barrage.
Protesters chanted "Murderer U.S., get out of Syria" and held banners that read "Murderer U.S., get out of the Middle East".
White House officials caution that Trump is not preparing to plunge the USA deeper into Syria.
USA ambassador to the United Nations Nikki Haley said on Friday the Trump administration was ready to take further steps if needed.
"We are prepared to do more but we hope that will not be necessary", she said.
Nancy Pelosi, the Democratic leader in the House, approved of the strike as a "proportional response" to Mr.al-Assad's brutality.
"The Russian side is halting the effect of the memorandum for prevention of incidents and ensuring safety of air flights during operations in Syria which was agreed with the United States", the Russian foreign ministry said.
Several lawmakers said Sunday that decision shouldn't entirely be up to Trump.
The Russian Defense Ministry said on Wednesday that the airstrike near Khan Shaykhun by the Syrian air force hit a terrorist warehouse that stored chemical weapons slated for delivery to Iraq, and called on the UN Security Council to launch a proper investigation into the incident.
Johnson said the situation in Syria has changed "fundamentally" following the chemical attack and the USA response.
"This is a President obsessed with toughness".
"I think the real failure here has been Russia's failure to live up to its commitments under the chemical weapons agreements that were entered into in 2013", Tillerson said.
As a former top prosecutor and head of the criminal law division at The Pentagon, he says motive is the first thing to look for.
"What did we want Assad to do next?" What did we hope Russian Federation would do?
Washington's allies have welcomed the strikes, while Russian Federation - a major supporter of Assad - has condemned them.
While the Syrian opposition applauded the U.S. cruise missile attack on the airbase near Homs, it said it should not be a one-off and was not enough on its own to stop government warplanes from hitting rebel-held areas. "Other than that, there is no change to our military posture", he said.
Russian officials have warned that the strikes dealt a "significant blow" to relations between Washington and Moscow, calling it a "flagrant violation of global law and an act of aggression" whose "consequences for regional and worldwide security could be extremely serious".
Trump issued the order to execute the cruise-missile strike at 3.45pm NY time, the person said. "The Trump administration must develop that comprehensive strategy".
"No", he said. "That wasn't discussed as any part of the deliberations".
