Beirut: Lebanon's army shot at an Israeli drone in south Lebanon on Wednesday, a military source and state media said, in a rare incident as tensions mount between the neighbours.

"A Lebanese army position in the district of Al Adeesa in south Lebanon saw a drone and they fired at it, and it returned to the occupied lands," a military source told AFP, referring to Israel.

The National News Agency said the army opened fire at the drone after "its violation of Lebanese airspace".
