Israeli soldiers detained two sisters of Saleh al-Arouri, a top leader of Hamas who was killed in Lebanon this month, Palestinian sources and the Israeli army said on Sunday.

The killing of Arouri, the deputy chief of Hamas, in a southern suburb of Beirut on January 2 was widely attributed to an Israeli drone strike, fuelling fears that Israel's war in Gaza could widen into a regional conflict.

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.

The U.S. administration has tasked a Dutch envoy with visiting Lebanon and meeting with Hezbollah’s leadership, a media report said on Friday.

“This is what happened over the past two weeks,” the Nidaa al-Watan newspaper reported.

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.

U.S. mediator Amos Hochstein proposed during his visit to Beirut on Thursday a cessation of hosilities between Lebanon and Israel and an eight-kilometer pullback by Hezbollah from the border, which would allow for the return of displaced residents on both sides of the border, the Nidaa al-Watan newspaper reported on 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.
