Theresa May has suggested the Government is considering joining potential military action against the Assad regime after a suspected Syrian chemical weapons attack that killed 70 people.

The Prime Minister described the attack as “barbaric” and that Britain “utterly condemns the use of chemical weapons in any circumstances”.

The Government has stressed the importance of the attack being investigated to determine who is culpable.

But Mrs May said that the regime, and its backers like Russia, “must be held to account” if found to be responsible.

Donald Trump said on Monday that a "major decision" would be made on the US response within 48 hours, adding that "nothing was off the table" following the attack in Douma, a besieged suburb of Damascus, which has sparked international outrage.
