US-led strikes on the Syrian regime on Saturday were aimed at "chemical weapons infrastructure" in what the US billed as a warning against Bashar Assad employing such weapons in the future.
The US, UK and France targeted a scientific research facility in the Damascus area, a chemical weapons storage facility west of the city of Homs and a third location that contained both a command post and a chemical weapons equipment storage facility in the same area, the US military said.
Here are some of the weapons the three Western countries used:
Four Royal Air Force Tornado jets using Storm Shadow missiles had taken part in the attack on the military facility near Homs where it was assessed Syria had stockpiled chemicals, Britain's Ministry of Defense (MoD) said.
It said initial indications were that the precision weapons and meticulous target planning had "resulted in a successful attack".
"Very careful scientific analysis" had been applied to maximize the destruction of stockpiled chemicals while minimizing any risk of contamination to surrounding areas.
"The facility which was struck is located some distance from any known concentrations of civilian habitation, reducing yet further any such risk," the MoD said in a statement.
As for France, its strikes involved 12 cruise missiles, fighter jets and warships. They were French President Emmanuel Macron's first major military decision since taking office a year ago.
The French presidency issued a video on Twitter showing what it said were Rafale warplanes taking off as part of the intervention.
The US reportedly used B-1 bombers in the strikes, but the American military declined to provide specifics.
The four-engine B-1 is capable of deploying air-launched JASSM cruise missiles, which carry 450 kilogram warheads and have a range of more than 370 kilometers.
"The strikes tonight were far harder than the ones last year, when the United States launched 58 missiles against the Shayrat air base following a chemical attack," Defense Secretary James Mattis said.
Syria fired surface-to-air missiles in response to the attacks but Russia said it did not.
