The British government has signaled that it was ready to back US military action against Syria, saying it was "highly likely" the Assad regime used chemical weapons on its own people and that such action could not go unchallenged.
According to the statement, May described the chemical attack on Douma in Eastern Ghouta as a "shocking and barbaric act which killed up to 75 people, including children, in the most appalling and inhumane way".
Britain would work with the US and France to coordinate an international response, it added.
May spoke with President Trump on Thursday night about the international response to Syria, and they "agreed that the Assad regime had established a pattern of dangerous behaviour in relation to the use of chemical weapons", according to the Downing Street.
On Wednesday, Trump appeared to suggest airstrikes were imminent, warning Russia, Syria's key ally, to "get ready" for military action.
But after being criticized for apparently telegraphing US intentions, Trump on Thursday attempted to blur the timing of any potential airstrikes on Syria.
