U.S. mediator Amos Hochstein said Monday that he held a "very constructive" meeting with Speaker Nabih Berri in Ain el-Tineh and that the U.S. is working with Lebanon and Israel on a "formula that brings an end to this conflict once and for all."

Hochstein added that U.N. resolution 1701 is “no longer enough” and that a new mechanism must be put in place to ensure it is implemented “fairly, accurately, transparently.”

Caretaker Prime Minister Najib Mikati has stressed that the only solution to the current conflict is “diplomacy.”

With U.S. mediator Amos Hochstein scheduled to arrive in Beirut on Monday amid major escalation in Lebanon, Parliament Speaker Nabih Berri has stressed that this visit is "the last chance before the U.S. elections to reach a solution" in the country.

Israeli airstrikes were targeting Beirut's southern suburbs on Sunday night, after the Israeli army warned that it would target Hezbollah's al-Qard al-Hassan financial institution in Haret Hreik, Shiyyah, Ghobeiri, Choueifat, Tahwitat al-Ghadir and Burj al-Barajneh.

The National News Agency reported 11 strikes on Beirut's southern suburbs, many of them targeting al-Qard al-Hassan. Other strikes hit the association in Lebanon's eastern Bekaa Valley and in the country's south, NNA added.

Israeli Prime Minister Benjamin Netanyahu on Saturday accused Iran and its "proxy Hezbollah" of trying to kill him and his wife, vowing that they would pay "a heavy price," after his office reported a drone targeted his residence in Caesarea.

Lebanese authorities said two people were killed in an Israeli strike on Saturday in Jounieh, north of Beirut, in the first strike on the area since Hezbollah and Israel started trading fire last year.

Top political leader of Hamas, Khalil al-Hayya, on Friday confirmed the death of the group’s leader, Yahya Sinwar.

Al-Hayya, in a televised statement, reiterated the Palestinian militant group’s stance that it will not release Israeli hostages captured in the group’s Oct. 7, 2023 attack on Israel until there is a cease-fire in the yearlong war in Gaza.

Free Patriotic Movement chief Jebran Bassil has called for unity to confront Israel, for a ceasefire, and for the election of a consensual president.

In remarks to al-Modon web portal, Bassil said the priority is for a ceasefire and for deterring a possible re-occupation of south Lebanon.

Lebanese Forces leader Samir Geagea accused the Lebanese government of becoming "a rescue committee" instead of a state and of allowing Iran to fight its battles from Lebanon.

In remarks published Friday in Asharq al-Awsat newspaper, Geagea said that Hezbollah has dragged Lebanon to where it is now, while Lebanese officials were "loafing around" instead of calling for the implementation of United Nations Security Council Resolution 1701.
