A group tracking the Syrian war said on Saturday that Islamist insurgents shot dead 56 members of Syrian government forces in a mass execution at an air base captured from the army earlier this month in northwestern Syria.
The Syrian Observatory for Human Rights said the mass killing at Abu al-Duhur air base happened a few days ago, citing sources on the ground. The air base in Idlib province was captured by an alliance of groups including the al Qaeda-linked Nusra Front on Sept. 9.
