President Barack Obama has announced that he will seek Congressional approval for military action against Syria.
The announcement came as a surprise to many who had thought that military strikes against Syria could be imminent.
But President Obama said the military operation could happen tomorrow, next week or in a month's time.
The White House said the refusal of British MPs to secure support for armed action had influenced its thinking.
