Watch: Hezbollah uses drones against Syrian rebels

Fars news agency says this is the first instance the group has used drones.

Hezbollah drone strikes Syrian rebel positions
With the three-and-a-half-year civil war in Syria spilling over into Lebanon, Hezbollah has upped its military capabilities in its fight against al-Qaida-affiliated Syrian rebels.
According to the Iranian Fars News Agency, the organization is now deploying drones – which until recently were used mainly for surveillance missions – to fight off Al-Nusra Front rebels.
The newly-released one-minute video shows a small structure, believed to be the Al-Nusra Front headquarters in Lebanon, being directly hit from the sky.
FNA reported that 23 terrorists were killed in the attack on the primarily-Sunni Arsal village, northeast of Beirut and dozens more were injured. The bombing also reportedly took the life of one of the group's main ringleaders.
Hezbollah pounded several other rebel positions during its crack down near the Lebanese–Syrian border, in what it said was a response to multiple attacks on Hezbollah checkpoints over the weekend. Al-Nusra claimed responsibility for the bombings, which left at least three dead.
Hezbollah drones have long been used for surveillance against Israel. In late 2012, the Israel Air Force shot down a small unmanned aerial vehicle as it flew over southern Israel. And in April of last year, Israel downed a Hezbollah drone off the coast of Haifa.
