"This massacre was a significant escalation in a pattern of chemical weapons use by that very bad regime", Trump alleged.
Speaking of Assad and his suspected role in last week's chemical weapons attack, Trump said, "These are not the actions of a man".
Chairman of the Joint Chiefs Gen. Joseph Dunford said in a news conference Friday that the three target areas included a scientific research center located in Damascus, a chemical weapons storage facility west of Homs and a nearby storage facility with chemical weapons equipment and an "important" command post.
The Russian ambassador said his country is being "threatened" and warned that "such actions will not be left without consequences". But on Friday, she added the USA has not decided on a possible response.
"We are trying to stop the murder of innocent people". The report said the Syrian air force uses the base to launch strikes on Eastern Ghouta.
As IS captured a wide swath of Iraq and Syria in 2014, the US began conducting airstrikes against the group and shifted its Syria policy to fighting the militants.
The US, UK, and France conducted air strikes against the Syrian government at around 9:00 PM EST on Friday night.

Syria fired surface-to-air missiles in response to the attacks, but Russian Federation apparently did not, the USA said, despite a threat from the country's ambassador to Lebanon that Moscow's forces would do so.
By supporting Assad, Russia's actions are "prejudicial to our security" and will let the Islamic State group "re-establish itself" - something that "we believe we need to take action to defend", said Pierce. "No nation can succeed in the long run by promoting rogue states ... and murderous dictators".
The Russians were warned beforehand, said French Defense Minister Florence Parly at a press conference on Saturday.
Mattis on Friday said he had seen enough evidence to conclude definitively that Assad's forces were behind the attack.
I will say this: The United States has a lot to offer, with the greatest and most powerful economy in the history of the world.
