The U.S. will train and equip 1,200 Syrian rebels in Turkey, Saudi Arabia, Qatar and Jordan to fight the Islamic State of Iraq and Syria, a U.S. Central Command official said Thursday.

Specifics of the U.S. plan to train moderate Syrians were first discussed by the Pentagon Wednesday, but at the time the training locations were not disclosed. According to the plan, up to 1,000 U.S. troops will work with the Syrians at the selected sites to train and equip them to combat the Islamic State, and then will return them to their cities inside Syria.
