Israel-Gaza-Lebanon live updates: 20 dead in Israeli strike on school, ministry says

After several members of the U.N. Interim Force in Lebanon were injured in airstrikes, Israeli Prime Minister Benjamin Netanyahu denied that the Israel Defense Forces was intentionally attacking the peacekeepers.

"The charge that Israel deliberately attacked UNIFIL personnel is completely false. It's exactly the opposite," Netanyahu said in a statement. "Israel repeatedly asked UNIFIL to get out of harm's way. It repeatedly asked them to temporarily leave the combat zone, which is right next to Israel’s border with Lebanon."

Netanyahu said he regrets "any harm done to UNIFIL personnel" and claimed the IDF was "doing its utmost to prevent such incidents."

"But the best way to assure the safety of UNIFIL personnel is for UNIFIL to heed Israel's request and to temporarily get out of harm's way," he said.

In the past 24 hours, 54 people have been killed and 258 have been wounded in Lebanon, according to the Lebanese Ministry of Public Health.

The total number of casualties since Israel's increased attacks on Lebanon in mid-September is now 2,309 people killed and 10,782 people injured, the ministry said.

A situational report from the Lebanese Prime Minister's Office on Monday said 200 airstrikes and shellings were recorded in various parts of Lebanon over the past 48 hours.

The Israel Defense Forces said in a release Monday that they found an underground compound in southern Lebanon stocked with "weapons, ammunition and motorcycles ready to be used in an invasion into Israel."

Israeli Prime Minister Benjamin Netanyahu said Israel "will continue to hit Hezbollah mercilessly in all parts of Lebanon" while visiting the Golani camp, which was hit by a Hezbollah drone Sunday evening, killing four IDF soldiers and injuring dozens.

"I want to make it clear: We will continue to hit Hezbollah mercilessly in all parts of Lebanon -- also in Beirut, all according to operational considerations. We have proven this in recent times, and we will continue to prove it in the coming days as well," Netanyahu said.

Netanyahu extended his condolences to the families of the fallen soldiers and said he would visit the injured later on Monday.

A Doctors Without Borders staffer has been killed in northern Gaza, the organization announced Monday.

Nasser Hamdi Abdelatif Al Shalfouh, 31, was struck by shrapnel Tuesday and died of injuries to his legs and chest two days later, according to the organization.

He is survived by his wife and two children.

In a statement, Doctors Without Borders condemned Israeli forces for having "systematically dismantled the health system in Gaza, impeding access to life-saving care for people."

"He was unable to receive the necessary level of care due to the hospital’s lack of capacity and an overwhelming number of patients in the facility," the organization said of Al Shalfouh.

Al Shalfouh joined Doctors Without Borders as a driver in March 2023, but had not been able to work for them recently as operations have been impacted by the war, the group said.

He is the seventh Doctors Without Borders staffer to be killed in Gaza since the war began, the organization added.

"We are horrified by the killing of our colleague which we strongly condemn and call yet again for the respect and protection of civilians,” the NGO said. “In this tragic moment, our thoughts are with his family and all colleagues mourning his death."
