The continued Israeli escalation in southern Lebanon will jeopardize the negotiations with Israel, a Lebanese official warned on Tuesday.

"The continued violations will either lead to us not participating in the negotiations or to our participation with the sole condition of a ceasefire," the official told Al-Jazeera.

MP Mohammad Raad has lamented that "the reality confirmed by the rounds of direct negotiations between Lebanon and the enemy (Israel) is that the ruling authorities have practically adopted the occupation's narrative against the resistance."

Prime Minister Nawaf Salam has stated that there is "increased American involvement in the efforts to solidify the ceasefire."

Hezbollah MP Hassan Fadlallah warned Tuesday that his group would fight any army unit formed by the U.S. and Israel to counter the resistance.

"If Israel and the U.S. manage to form a collaborator army to fight the Resistance, we will fight it just like we fight Israel," Fadlallah said in a press conference, as he warned against free "gifts" to the U.S.

At least six people were killed Tuesday and 3 others wounded in strikes on south Lebanon.

A strike on a home in Kfarsir killed four people and wounded two, while a separate strike targeting a car in Harouf killed one person and wounded another.

Israeli strikes have killed more than 3,000 people in Lebanon since the start of the war between Hezbollah and Israel on March 2, the health ministry said on Monday, after an April 17 ceasefire failed to stop the fighting.

A security agreement that is in the works will include "timetables for disarming all illegal militias, starting with Hezbollah and extending to the smallest Palestinian faction," a Lebanese government source said.

President Joseph Aoun said Monday that he would do the 'impossible' in order to stop the war with Israel, after a ceasefire and direct talks failed to end the fighting.

"The framework that Lebanon has set for the negotiations consists of an Israeli withdrawal, a ceasefire, the deployment of the army along the border, the return of the displaced, and economic aid," Aoun said in a statement.

Israel has no military solution to the Hezbollah drone threat even if troops occupy all of south Lebanon, Israeli reports said.

A security source told Israel's Kan public broadcaster that a political breakthrough is needed, as occupation will not solve the drones' problem.

Druze leader Walid Jumblat on Monday described the ceasefire between Lebanon and Israel as an "illusion."
