Israel’s defense minister has told his U.S. counterpart that time is running out for an agreement with Hezbollah to halt the fighting along the Israel-Lebanon border.

Yoav Gallant told Defense Secretary Lloyd Austin that “the possibility for an agreed framework in the northern arena is running out as Hezbollah continues to ‘tie itself’ to Hamas.”

Israeli Prime Minister Benjamin Netanyahu has said that the current situation on the border with Lebanon is not sustainable.

"The existing situation will not continue. We will do everything necessary to return our residents safely to their homes," he said during a weekly Cabinet meeting.

Hezbollah said Sunday that it fired dozens of Katyusha rockets at the Rawya barracks in the Israeli-annexed Golan Heights in response to attacks on Lebanese towns, especially on the town of Sarafand which is distant from the border.

Hezbollah's second-in-command warned on Saturday that an all-out war by Israel aimed at returning 100,000 displaced people to their homes in areas near the Lebanon border would displace "hundreds of thousands" more.

Sheikh Naim Qassem, number two in the Iran-backed Lebanese group, was speaking after Israeli Defense Minister Yoav Gallant said Israel was determined to restore security to its northern front.

Hezbollah said Saturday that it fired dozens of Katyusha rockets at an Israeli artillery and precision missile base in Yiftah Elifelet northwest of Lake Tiberias, deep in northern Israel.

U.S. mediator Amos Hochstein will soon visit Tel Aviv as well as Lebanon, al-Jadeed television quoted sources as saying.

Hezbollah targeted Friday military positions in northern Israel and in the occupied Shebaa and Kfarshouba regions with suicide drones and other weapons while Israeli warplanes raided twice the southern town of Bint Jbeil.

The jets targeted early Friday a house and later the al-Wadi region in Bint Jbeil, causing no casualties, the National News agency said. Later in the day, artillery shelled the southern border town of Kfarshouba.

Hezbollah’s response to the assassination of its military chief Fouad Shukur killed 22 and wounded 74 others from Israel’s Unit 8200 intelligence department, the pro-Hezbollah al-Mayadeen TV quoted “credible European security sources” as saying.

Lebanese Forces leader Samir Geagea has accused Hezbollah of “attempting to promote the idea that it would seize control of the various joints of the state in return for it (Hezbollah) offering concessions in the South.”

The leader of the Palestinian Hamas group thanked Lebanon’s Hezbollah chief for his support in the ongoing war with Israel in a letter released Friday by Hezbollah’s media office.

Yahya Sinwar’s letter came in response to a message sent earlier by Hezbollah leader Sayyed Hassan Nasrallah in which he paid his condolence for the July killing of top Hamas official Ismail Haniyeh during a visit to Iran.
