President Donald Trump has condemned the “heinous” suspected poison gas attack in Syria and said he will make a decision on the US response within 24 to 48 hours.
Speaking in the White House Cabinet Room, Mr Trump vowed to find out who is responsible for the attack that reportedly killed at least 40 people.
Mr Trump said during a Cabinet meeting with reporters: “If it’s Russia, if it’s Syria, if it’s Iran, if it’s all of them together, we’ll figure it out.”
Opposition activists said 40 people died in the chemical attack late on Saturday in the suburbs of the Syrian capital and blamed it on the Syrian government, which is closely allied with Russia.
Syria has blamed Israel for a missile attack on a central air base early on Monday that reportedly killed 14 people, including three Iranians.
