The Observatory said the cause of the explosion was unknown, as well as its target.
ISI Image Sat International shared satellite images with Fox News, showing the Barzah Research and Development Center before and after the airstrikes. The images reveal crushing damage to structures at the target site. "But it's definitely not in their interests, nor do I think they want to continue escalating things with Trump, or with any other western states because at the end of the day, they've got a country which is nearly completely destroyed".
"We are confident that we have crippled Syria's chemical weapons program".
The attacks, launched in retaliation for a suspected poison gas attack a week ago, destroyed facilities in Homs and the Barzah Research Centre.
The United States, Britain, and France have argued that military action was necessary after Assad's forces had used toxic gases multiple times in violation of global law. Could not have had a better result.
"So, today the nations of Britain, France and the United States of America have marshaled their righteous power against barbarism and brutality", said the president in a televised address from the White House. Hill says in 2013, the Russians promised to oversee the withdrawal of chemical weapons from Syria.
Defense Secretary James N. Mattis told reporters Friday night that the administration still did not know whether a Syrian attack on a rebel-held area near Damascus last Saturday involved an illegal nerve agent as well as chlorine.
The OPCW itself had declared that the Syrian regime's chemical weapons stockpile had been removed in 2014, only to confirm later that sarin was used in a 2017 attack in the northern town of Khan Sheikhun.
"We deployed 105 weapons against three targets that will significantly impact the Syrian regime's ability to develop, deploy and use chemical weapons in the future", said Lt. Gen. Kenneth McKenzie, Director of the Joint Staff during a Pentagon Press Conference Saturday.
Pentagon officials said the allied forces' attack was met with no resistance. Urging the Security Council to assume its responsibilities, Guterres said a "lack of accountability" emboldens those who would use such chemical weapons by providing them with the "reassurance of impunity". Of the United States ships, cruiser Monterey fired 30 Tomahawks, destroyers Higgins and Laboon fired 23 and seven respectively, and the attack submarine John Warner fired six.
Earlier, the US, Great Britain and France claimed the strikes had been conducted in response to an alleged chemical weapons attack in Douma, a suburb of the Syrian capital.
Russian Federation had said it would consider supplying S-300 surface to-air missile systems to Syria following the Western strikes, but this was not discussed at the meeting with Mr Assad, agencies reported. McKenzie says the missiles were fired after the "last impact" was over.
Trump said a small American force over the past year has virtually eliminated Islamic State control over what once was a vast territory spanning parts of Syria and Iraq. "So they had no material impact on the strike".
