Rebel Military Chief Says Hezbollah Fighters Are 'Invading' Syria

Says more than 7,000 are involved in the assault on the town of Qusair

The military chief of the main umbrella group of Syrian rebels, the Free Syrian Army, has accused Hezbollah fighters of "invading" Syria in a BBC interview.

Gen Selim Idriss said that more than 7,000 fighters of the Lebanese Shia movement were taking part in attacks on the rebel-held town of Qusair.

Gen Idriss made an urgent appeal for more weapons "to defend our citizens".

The UN Human Rights Council condemned government attacks on Qusair, and the involvement of foreign fighters.
