Israeli forces fired on two positions used by UN peacekeepers in southern Lebanon on Thursday and at another one on Wednesday, the UN force said, as Israel pressed its assault on Hezbollah and told Lebanese civilians not to return to homes in the south.
The UNIFIL force said two of its peacekeepers were injured in one of the incidents, when an Israeli tank fired at an observation tower at the force's main headquarters in Naqoura, hitting the tower and causing them to fall.
There were no casualties in the other two incidents, a UN source said.
"Any deliberate attack on peacekeepers is a grave violation of international humanitarian law," UNIFIL said in a statement, adding that it was following up with the Israeli military.
There was no immediate comment from the Israeli military, which is waging a widening offensive in Lebanon against Hezbollah.
Israel says its Lebanon offensive aims to secure the return home of tens of thousands of Israelis who evacuated northern Israel due to cross-border rockets launched by Hezbollah, which opened fire a year ago to support Hamas in Gaza.
UNIFIL said Israeli soldiers had also fired at a UN position in Ras Naqoura "hitting the entrance to the bunker where peacekeepers were sheltering, and damaging vehicles and a communications system.”
"An IDF drone was observed flying inside the UN position up to the bunker entrance," UNIFIL said. The previous day, Israeli forces had "fired at and disabled the position’s perimeter-monitoring cameras,” it added. They also deliberately fired at and damaged another position, it said.
