WASHINGTON (Reuters) - U.S. Secretary of State John Kerry said on Sunday tests showed that sarin nerve gas was used in a deadly August 21 chemical attack near Damascus as he sought to build the case to convince sceptical lawmakers to authorize a military strike against the Syrian government.
Kerry made the disclosure in a series of television interviews a day after President Barack Obama delayed imminent military action in Syria to seek approval first from the U.S. Congress - a decision that puts any strike on hold for at least nine days.
