The United Nations Interim Force in Lebanon said Thursday that Israeli forces fired on three peacekeeper bases in the south of the country, injuring two troops.

"UNIFIL's Naqoura headquarters and nearby positions have been repeatedly hit" amid fighting between Israel Defense Forces and Hezbollah in the area, the mission said in a post to X.

Two peacekeepers were injured at the Naqoura position "after an IDF Merkava tank fired its weapon toward an observation tower," the mission wrote, "directly hitting it and causing them to fall. The injuries are fortunately, this time, not serious, but they remain in hospital."

Elsewhere, UNIFIL said IDF fire on its camp in Labbouneh hit the entrance to a bunker where peacekeepers were sheltering, damaging vehicles and a communications system.

The IDF also fired at and disabled the perimeter-monitoring cameras at Labbouneh, UNIFIL said. An IDF drone was observed above the position, the mission added.

"Any deliberate attack on peacekeepers is a grave violation of international humanitarian law and of Security Council resolution 1701," UNIFIL said, referring to the 2006 U.N. Security Council agreement that sought to end the last major cross-border war between Israel and Hezbollah.

"We are following up with the IDF on these matters," it added.

At least 28 Palestinians were killed in a single attack on a school in Deir al-Balah in the central Gaza Strip, according to the Hamas-run Gaza Health Ministry.

Children are believed to be among the casualties in the attack on the Rufaydah school. The Israel Defense Forces said it was targeting a Hamas "command and control center" in what it called a "precise strike."

The strike occurred in the central region of the devastated strip, where Palestinians from the north have been ordered to evacuate by the IDF.

In the north, Israel is continuing an intense military operation in the Jabalia refugee camp, which is now sealed off and under IDF siege. This is the fourth major IDF operation in Jabalia since the start of the war.

The IDF, meanwhile, said it downed a drone launched into Israel from Gaza, with no injuries reported.

Around 25% of Lebanese territory is now under Israel Defense Forces evacuation orders, the United Nations said.

New "displacement orders" are being "issued on a daily basis," the United Nations Office for the Coordination of Humanitarian Affairs said in a situation update, noting that more than 100 villages and urban areas in southern Lebanon are affected.

A total of 1.2 million people across the country have been displaced by Israeli air and ground attacks, the report said, citing OHCHR figures.

The Israel Defense Forces issued another evacuation order in an area of Dahieh in Beirut, Lebanon, right after midnight Thursday local time.

"You are located near Hezbollah facilities and interests, against which the IDF will operate in the near future," the order read.

"For your safety and the safety of your family members, you must evacuate this building and the surrounding buildings immediately and stay away from them for a distance of no less than 500 meters," the IDF added.
