On Tuesday evening US President Barack Obama said he would postpone a vote in Congress on US military action against the Syrian government, which he accuses of firing poison gas munitions into a Damascus suburb controlled by rebels.
He also pledged to explore a Russian plan to remove Syria's chemical arsenal but voiced skepticism about it and urged Americans to support his threat to use military force if needed.
