A warplane on Friday bombed the Syrian town of Khan Sheikhoun, where a chemical attack killed scores of people this week and prompted USA missile strikes, a witness in the rebel-held area and a war monitoring group said.
A spokesman for the Iranian Foreign Ministry, quoted by ISNA news agency, said: "Iran strongly condemns any such unilateral strikes. such measures will strengthen terrorists in Syria. and will complicate the situation in Syria and the region". Obama had declared the use of such weapons a "red line".
Tonight I call on all civilised nations in seeking to end the slaughter and bloodshed in Syria and also to end terrorism of all kinds and all types.
Russia's military on Friday said a USA strike on a regime air base in Syria was ineffective but announced Syrian air defences would be strengthened to shield the country's key infrastructure.
Rep. Barbara Lee (D., Calif.) called the move an "act of war" and said Congress must meet to debate the Syrian issue.
The 59 Tomahawk cruise missiles were launched about 4:40 a.m. local time from the U.S. Navy destroyers USS Ross and USS Porter, which are deployed in the eastern Mediterranean.
Authorities are assessing Tuesday's chemical attack in Syria's Idlib province, which officials estimate killed more than 70 people and injured another 400.
Six Syrian soldiers were killed.
Kremlin spokesman Dmitry Peskov, in his regular Friday morning briefing, said the US strike constituted "aggression against a sovereign state in violation of worldwide law".
Putin spokesman Dmitry Peskov said in Friday's statement carried by Russian news agencies that Putin believes the USA launched the strikes under a "far-fetched pretext". "S. relations, which are already in a deplorable shape", Peskov said. He added that the attack creates a "serious obstacle" for creating an worldwide coalition against terrorism.
"The airbase was nearly completely destroyed - the runway, the fuel tanks and the air defences were all blown to pieces", the Syrian Observatory for Human Rights said. Although they support opposing sides in the war between Assad and rebels, Washington and Moscow both say they share a single main enemy, Islamic State.Tuesday's attack was the first time since 2013 that Syria was accused of using sarin, a banned nerve agent it was meant to have given up under a Russian-brokered, United Nations -enforced deal that persuaded Obama to call off air strikes four years ago.Video depicted limp bodies and children choking while rescuers tried to wash off the poison gas. The missiles struck the Syrian airfield where the plane that carried the chemical weapon in this week's attack that killed dozens - including children - took off from. It serves as a crucial link to make sure the increasingly crowded Syrian airspace doesn't see any accidental collisions or attacks on each other.
Maj. Jamil al-Saleh, a U. "We have very high confidence that the attacks involved the use of sarin nerve gas", U.S. Secretary of State Rex Tillerson told reporters late Thursday.
The former president warned Assad not to cross his "red line" and provoke a United States military strike, but then failed to get the support of Congress to carry out punitive strikes against the Syrian government so backed down.
He opted instead for a Russian-backed plan that was supposed to remove and eliminate Syria's chemical weapons stockpiles. Russian Federation has said the toxic agents were released when a Syrian airstrike hit a rebel chemical weapons arsenal on the eastern outskirts of Khan Sheikhoun, and that blame should not be apportioned until a full investigation has been carried out.
The decision from America's new Commander-in-Chief came 77 days into his presidency, after Russian Federation used their veto on a United Nations Security Council resolution calling for an investigation into the chemical atttack.
It said the USA action was taken under the "pretext" of the chemical strike. Trump said "peace and harmony will prevail" so long as the USA continues to stand for justice. "We pray for the lives of the wounded and for the souls of those who have passed, and we hope that as long as America stands for justice, that peace and harmony will in the end prevail", he said.
The White House was quick to paint the decision as limited to deterring the use of chemical weapons, and not part of a broader military campaign to remove Mr. Assad by force. But the vote was cancelled because of differences among the 15 members.
