Rebels Accuse Syrian Government Of Gassing Up to 1,300 People

UN chemical weapons investigators arrived in Damascus earlier this week

Syria's opposition accused President Bashar al-Assad's forces of gassing many hundreds of people - by one report as many as 1,300 - on Wednesday in what would, if confirmed, be the world's worst chemical weapons attack in decades.

Western and regional countries called for U.N. chemical weapons investigators - who arrived in Damascus just three days ago - to be urgently dispatched to the scene of one of the deadliest incidents of the two-year-old civil war.
