Hezbollah leader Sayyed Hassan Nasrallah stressed Sunday that Hezbollah does not not fear war or U.S. and Israeli threats, while emphasizing that his group will not negotiate over the situation on the border before the end of Israel’s war on Gaza.

“We will continue and our front is inflicting defeats on the enemy,” Nasrallah said in a televised speech commemorating Hezbollah senior military commander Wissam Tawil, who was assassinated by Israel on Monday.

Hezbollah on Sunday appeared to have intensified its attacks on Israeli posts compared to the past few days, hours before a speech by Hezbollah chief Sayyed Hassan Nasrallah marking one week since Israel’s assassination of senior Hezbollah military commander Wissam Tawil.

In a statement, Hezbollah said it attacked an Israeli force in the Kfar Yuval area in northern Israel, causing deaths and injuries.

Israeli troops on Sunday killed three militants who crossed in from Lebanon into the occupied Shebaa Farms, the Israeli army said, as tensions surge on the 100th day of the Israel-Hamas war.

Since Israel's war with Hamas in the Gaza Strip erupted on October 7, the Israel-Lebanon border has seen near-daily exchanges of fire between Hezbollah militants and Israeli forces.

The Israeli army on Saturday waged a "preemptive attack" on south Lebanon and its warplanes attacked "Hezbollah targets,” Israel’s Channel 12 said.

Lebanon’s National News Agency for its part said that Israeli warplanes destroyed a house in the border town of Yarin, causing casualties, amid reports of an airstrike on the border town of Mays al-Jabal and artillery shelling on the outskirts of Aita al-Shaab and Rmeish.

U.N. Under-Secretary-General for Peace Operations Jean-Pierre Lacroix has concluded a four-day visit to Lebanon.

Caretaker Prime Minister Najib Mikati on Friday noted that pacifying the situation in south Lebanon without taking into consideration what’s happening in Gaza would be “illogical.”

“We have told all envoys that talking about pacification exclusively in Lebanon is an illogical thing,” Mikati said at the beginning of a Cabinet session.

Parliament Speaker Nabih Berri has said that U.S. mediator Amos Hochstein has carried “ideas” to Lebanon, not a complete “proposal.”

“In turn, we proposed other ideas,” Berri added, in an interview with Asharq al-Awsat newspaper published Friday.

Hezbollah condemned Friday American and British air strikes on rebel-held Yemen.

The attacks, in response to Houthi's attacks on Red Sea shipping, killed at least five people and wounded six.

The Israeli army bombed Friday several border towns in south Lebanon, as U.S.-led airstrikes on Yemen's Houthi rebels raised fears of a regional conflagration.

The Israeli artillery shelled Mays al-Jabal, Houla, Dhaira and Tayr Harfa.

New U.S. Ambassador Lisa A. Johnson has arrived in Lebanon, the U.S. embassy in Beirut said.

Johnson is a former U.S. Ambassador to Namibia and more recently held leadership positions in the State Department’s Bureau of International Narcotics and Law Enforcement in Washington.
