Syrian state media have sharply criticized Jordan for hosting U.S.-backed training of Syrian rebels seeking to topple President Bashar Assad, warning that Amman risks falling into the "volcanic crater" of Syria's conflict. The stern warning issued Thursday by state radio and in a front-page editorial in the daily al-Thawra, the mouthpiece of the Syrian government, will likely aggravate Jordan's security fears over the civil war in its northern neighbor.
