President Trump has ordered a military strike, in alliance with the UK and France, on Syria's Assad regime following a suspected chemical weapon attack in Douma on April 7 that killed at least 45 people.
The military response comes following an announcement on Friday by the White House that the US Government had proof that the Assad regime had carried out the attack.
Trump, speaking at press conference in Washington, said: "What kind of nation wants to be associated with mass murder of innocent men, women and children?
"America does not seek an indefinite presence in Syria. We look forward to the day when we can bring our warriors home."
British Prime Minister Theresa May has issued a statement in accordance with the UK's part in the military strike: "This persistent pattern of behaviour must be stopped - not just to protect innocent people in Syria from horrific deaths and casualties caused by chemical weapons, but also because we cannot allow the erosion of the international norm that prevents the use of these weapons.
"We have sought to use every possible diplomatic channel to achieve this."
Reuters is reporting that witnesses heard large explosions in the Barzah district of Damascus, which is said to be the site of a Syrian scientific research centre.
