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.
