Prime Minister Nawaf Salam commented Tuesday on the resumption of Israeli-Lebanese negotiations in Washington by saying that "what remains is to consolidate a ceasefire throughout Lebanon."

The path of negotiation is "the least costly for the country, especially since wars throughout history have ended with a victor and a vanquished, or with negotiations to resolve the conflict," President Joseph Aoun said on Tuesday.

Parliament Speaker Nabih Berri praised Tuesday Iran for insisting that a ceasefire in Lebanon remains a key condition for any deal with the United States.

Iran's parliament speaker and chief negotiator Mohammad Bagher Ghalibaf had said on Monday night that he and Berri had spoken by phone.

A strike on a car on the Khardali road in south Lebanon killed a man, his son and his daughter, who were students, as he drove them back from university exams in Beirut to the southern border village Qlayaa, where some residents were still holding out despite Israeli evacuation orders.

Theodosia Karam, the daughter, had exams at the Lebanese University in Hadath and left with her father and brother after Israel threatened Beirut's southern suburbs. They drove to their hometown, Qlayaa.

Israel said Monday it would once again target Beirut's southern suburbs, a Hezbollah stronghold mostly spared heavy attacks since April, as it stages its deepest incursion into Lebanon in two decades.

The Saudi Ministry of Foreign Affairs on Monday expressed the Kingdom's condemnation of Israel's escalating attacks in Lebanon and its "categorical rejection of the Israeli incursion Lebanon's territory and the violation of its sovereignty."

Negotiation with Israel is "safer than war, as we have witnessed and continue to witness the horrors and consequences of war," President Joseph Aoun said Monday.

Iranian Foreign Minister Abbas Araghchi said Monday that attacking Lebanon violates the ceasefire "on all fronts," warning that "the U.S. and Israel are responsible for the consequences of any violation," after Israeli officials threatened to bomb Beirut's southern suburbs.

"The ceasefire between Iran and the US is unequivocally a ceasefire on all fronts, including in Lebanon. Its violation on one front is a violation of the ceasefire on all fronts. The US and Israel are responsible for the consequences of any violation," Araghchi wrote on X.

The latest U.S. push for a ceasefire in Lebanon has fizzled just as Israel is expanding its ground invasion and seeking a U.S. green light to conduct massive strikes on Hezbollah targets in Beirut's southern suburbs, sources told U.S. news portal Axios.

President Joseph Aoun is leading intensive efforts with the Americans in an attempt to reach a ceasefire or de-escalation and to halt the Israeli advance, the al-Modon news portal reported on Sunday
