The United Nations chief Antonio Guterres says the Security Council must prevent Syria “spiraling out of control”.
Meanwhile, US President Donald Trump told Russia in an early morning tweet to “get ready” for “nice and new and ‘smart!'” missile attacks in Syria, after an alleged gas attack on the last rebel stronghold in the country.
White House Press Secretary Sarah Sanders says no timetable has been set for potential military action against the Syrian government, and that all options are on the table.
