“As the United States begins to deepen ties with moderate Syrian rebels to combat the extremist group ISIS, also known as the Islamic State, a key component of its coalition appears to have struck a non-aggression pact with the group.

“According to Agence France-Presse, ISIS and a number of moderate and hard-line rebel groups have agreed not to fight each other so that they can focus on taking down the regime of Syrian President Bashar Assad. Other sources say the signatories include a major U.S. ally linked to the Free Syrian Army. Moreover, the leader of the Free Syrian Army said Saturday that the group would not take part in U.S. plans for destroying the Islamic State until it got assurances on toppling Assad.

“The deal between ISIS and the moderate Syrian groups casts doubt over President Barack Obama’s freshly announced strategy to arm and train the groups against ISIS.” *
