Israeli Prime Minister Benjamin Netanyahu warned on Sunday that Hezbollah was seeking to rearm and that Israel would exercise its right to self-defense under last year's ceasefire accord if Lebanon failed to disarm the militant group.
At the start of a cabinet meeting Netanyahu said Israel would "act as necessary", if Lebanon does not take steps to prevent its territory from becoming a renewed front.
The US brokered a truce in November 2024 between Lebanon and Israel after more than a year of conflict sparked by the war in Gaza, but Israeli strikes across the border have continued sporadically.
The Israeli military said in a statement on Sunday that it had killed four Hezbollah members.
Lebanese army sources told Reuters they had blown up so many Hezbollah arms caches that they had run out of explosives and they expect to complete their sweep of the country's south by the end of the year.
Hezbollah has publicly committed to the ceasefire and has not opposed the seizures of unmanned weapons caches in the south. It has not fired on Israel since the November truce.
However, it insists the disarmament, as mentioned in the text, only applies to the south of Lebanon and has hinted conflict is possible if the state moves against the group.
Earlier Sunday, Israeli Defense Minister Israel Katz said the Lebanese government must fulfill its commitment to disarm Hezbollah and remove it from southern Lebanon.
Katz also said maximum enforcement efforts would continue and intensify to protect Israeli residents in the north.
