At least 20 Syrian Security Officials and pro-government fighters killed in an I.S. Attack on Tayfur Airport in Homs Province.

The head of the Britain-Based Monitor, Rami Abdel Rahman, said IS was using “successive attacks” to wear out regime forces, and that clashes were ongoing.

The Militants retook Palmyra in Central Syria last week just eight months after the army backed by Russia drove them out, but the Militants recently launched an offensive attempting to recapture the city.
