Israeli troops fought fierce battles with Hezbollah fighters on Friday in different areas in south Lebanon, including a coastal town that is home to the headquarters of U.N. peacekeepers.

A spokesman for the U.N. peacekeeping force known as UNIFIL told The Associated Press that they are monitoring “heavy clashes” in the coastal town of Naqoura and the village of Chamaa to the northeast.

UNIFIL’s headquarters are located in Naqoura in Lebanon’s southern edge close to the border with Israel.

“We are aware of heavy shelling in the vicinity of our bases,” UNIFIL spokesman Andrea Tenenti said. Asked if the peacekeepers and staff at the headquarters are safe, Tenenti said: “Yes for the moment.”

Several UNIFIL posts have been hit since Israel began its ground invasion of Lebanon on Oct. 1, leaving a number of peacekeepers wounded.

The fighting came a day after the International Criminal Court issued arrest warrants for Israeli Prime Minister Benjamin Netanyahu, his former defense minister and a Hamas military leader, accusing them of war crimes and crimes against humanity over their 13-month war in Gaza and the October 2023 attack on Israel respectively.

The warrant marked the first time that a sitting leader of a major Western ally has been accused of war crimes and crimes against humanity by a global court of justice.

Israel’s war has caused heavy destruction across Gaza, decimated parts of the territory and driven almost the entire population of 2.3 million people from their homes, leaving most dependent on aid to survive.

Israel launched its war in Gaza after Hamas-led militants stormed into southern Israel on Oct. 7, 2023, killing some 1,200 people, mostly civilians, and abducting another 250. Around 100 hostages are still inside Gaza, at least a third of whom are believed to be dead.

Israel has also launched airstrikes against Lebanon after the Hezbollah militant group began firing rockets, drones and missiles into Israel the day after Hamas’ attack last October. A full-blown war erupted in September after nearly a year of lower-level conflict.
