Beirut, March 20 (IANS): The Nusra Front, an affiliate of the Al Qaeda in Syria, said on Friday that it killed 12 members of the Lebanese Shia Islamist militant group Hezbollah in the region of al-Qalamoun, north of Damascus, on the border with Lebanon.

On a Nusra Front Twitter account, the authenticity of which has not been verified, the group revealed that it killed members of the "apostate gang", referring to Hezbollah, by targeting the 12 victims with a missile, five of whom were allegedly in a tent, Efe news agency reported.

The Syrian Observatory for Human Rights reported on Thursday night that the Nusra Front had attacked positions of the Syrian regime forces and its allies in the highlands of al-Qalamoun, resulting in an unknown number of casualties.
