REYHANLI, Turkey/WASHINGTON (Reuters) - Hundreds of Syrian rebels are approaching the start of U.S. training to battle Islamic State, without knowing whether or how Washington would come to their aid on the battlefield and as other rebel leaders say the proxy army could spark opposition infighting.
The U.S. plan to train and arm a force that is expected to eventually total more than 15,000 troops and to get underway in the coming weeks is a major test of President Barack Obama's strategy of engaging local partners to combat extremists.
