BEIRUT — The Israeli military says its air force was on Monday striking targets of the Iranian-backed terrorist group Hezbollah “deep inside Lebanon,” where residents reported explosions near the northeastern city of Baalbek.

The strikes are among the deepest into Lebanon since the Israel-Hamas war began more than four months ago. They come a day after Israel’s defense minister, Yoav Gallant, vowed to step up attacks on Lebanon’s Hezbollah even if a cease-fire is reached with Hamas in the Gaza Strip.

Lebanese security officials said Israel’s air force carried out three airstrikes on the outskirts of the village of Buday, near Baalbek, targeting a convoy of trucks. Buday is a Hezbollah stronghold. There was no immediate word on casualties.

A Hezbollah official confirmed that three strikes hit near Baalbek. The officials spoke on condition of anonymity because he was not authorized to talk to reporters.

The Israeli army says further details will follow.

The airstrikes near Baalbek came hours after Hezbollah said that it on Monday shot down an Israeli drone over its stronghold in a province in southern Lebanon.

Another missile fired by Hezbollah toward the drone was intercepted by Israel, and landed near a synagogue in a town close to Nazareth in northern Israel. There were no injuries or damage.

Hezbollah has been exchanging fire with Israeli troops along the border since the Israel-Hamas broke on October 7.

The strike on Baalbek, because of its location deep inside Lebanon, is the most significant one since the early January airstrike on Beirut that killed top Hamas official Saleh Arouri.

Hezbollah, which has been exchanging fire with Israel throughout the war in Gaza, has said it will halt its nearly daily attacks on Israel if a cease-fire is reached in Gaz
