Russian jets have targeted a headquarters of an armed opposition faction that receives US support in a mountainous area in Syria's Hama.

Six elements of al Ezza Army were killed in the Russian raid, said Ramy Abdel el Rahman, the director of the Syrian Observatory for Human Rights (SOHR), in statements to the US-funded Radio Sawa Monday.

Al Ezza Army has been engaged in fierce clashes with Syrian regime troops in Hama for weeks now.
