The IDF killed three members of the Lebanese Army, including a brigadier general, in a strike on a vehicle in southern Lebanon on Saturday, raising concerns that a recently negotiated ceasefire could be put at risk.

The strike hit a military vehicle traveling in the Nabatieh area, killing a brigadier general, a captain and a soldier, according to the Lebanese Armed Forces, which condemned the attack.

Lebanese officials accused Israel of undermining attempts “to reach a solution that would restore stability, establish a comprehensive ceasefire and lead to the Israeli withdrawal from the occupied Lebanese territories.”

“The continued, deliberate, and repeated Israeli aggression against Lebanon, its people and its army only strengthen our resolve, faith and determination,” the Lebanese army said in a statement, according to the Times of Israel.

The IDF confirmed that it carried out the strike, saying the vehicle had been “moving suspiciously” in a combat zone where Israeli forces were facing threats from Hezbollah terrorists operating from Lebanon.

“The IDF had received concrete indications that Hezbollah would direct fire toward IDF soldiers from the same area,” it said in a statement on X.

“In light of the threat posed to the soldiers, the vehicle was struck.”

The strike came after an IDF soldier was killed by Hezbollah terrorists in a separate incident in southern Lebanon over the weekend.

“The IDF operates against the Hezbollah terrorist organization, not against the Lebanese Army,” the Israeli military said, adding that the incident would be reviewed.

Israel has been conducting operations against the Iranian-backed Hezbollah terrorist group in southern Lebanon since March, after opening another front in its war against Iran.

Israel has stressed that it is not fighting the Lebanese government and said it is “not against the Lebanese Army,” which under the US-brokered ceasefire agreement reached Wednesday was expected to take control of areas in southern Lebanon that had been heavily influenced by Hezbollah.

The deadly incident involving Lebanese forces could further complicate already stalled US-led diplomatic efforts aimed at ending the wider conflict.
