THE EXCLUSIVE report is from Josh Rogin at Foreign Policy:

A secret State Department cable has concluded that the Syrian military likely used chemical weapons against its own people in a deadly attack last month, The Cable has learned.

United States diplomats in Turkey conducted a previously undisclosed, intensive investigation into claims that Syrian President Bashar al-Assad used chemical weapons, and made what an Obama administration official who reviewed the cable called a “compelling case” that Assad’s military forces had used a deadly form of poison gas.
