Hezbollah said it targeted Israeli troops in a south Lebanon border village on Monday, as the Israeli army said it had deployed another division to participate in operations in Lebanon.

Hezbollah fighters "bombed... a gathering of Israeli forces in the Maroun al-Ras park with a rocket salvo", the group said in a statement, after announcing separately it had targeted several areas of northern Israel and military positions across the border.

Hezbollah said its fighters pushed away Israeli troops that attempted to storm into a Lebanese border village early Sunday, in the latest clashes after Israel announced ground operations earlier this week.

Caretaker Prime Minister Najib Mikati called for "pressure on Israel" for a ceasefire as a new Israeli strike hit the capital's southern suburbs on Sunday.

Mikati said he backed U.S. and French efforts for a truce, as the official National News Agency reported a strike south of Beirut.

Israeli strikes killed 23 people across Lebanon on Saturday, the health ministry has said.

A fireball lit up the sky and smoke billowed over Beirut on Sunday as Israel unleashed intense strikes targeting the capital's southern suburbs, almost a year since the Hamas attack that sparked war in Gaza.

In Gaza, Israel's military said it encircled the Jabaliya area of northern Gaza after indications Hamas was rebuilding despite nearly a year of devastating air strikes and fighting.

U.S. mediator Amos Hochstein has denied that Washington has given a “green light” to Israel regarding its ongoing attack on Lebanon.

The head of the United Nations refugee agency arrived in Lebanon on Saturday on a "solidarity" visit for those affected by Israeli bombardment, decrying a "terrible crisis" that requires international support.

UNHCR chief Filippo Grandi said on social network X that "Lebanon faces a terrible crisis" as "hundreds of thousands of people are left destitute or displaced by Israeli air strikes," adding: "I have come here in solidarity with those affected, to support the humanitarian effort and to ask for more international help."

Nearly 375,000 people have crossed from Lebanon into Syria, fleeing Israeli bombardment, in less than two weeks, Lebanese officials said.

The government's crisis management unit, citing figures from Lebanese General Security, said 374,621 people — Lebanese citizens and Syrians living in Lebanon — have crossed into Syria since Sept. 23, when Israel intensified its air bombardment campaign in Lebanon.

At least four hospitals in Lebanon announced the suspension of work amid ongoing Israeli bombardment, while Hezbollah-affiliated rescuers said 11 personnel were killed in Israeli raids in south Lebanon.

After Israeli bombardment forced them to flee their homes in haste, displaced Lebanese have been asking volunteers to enter their bombed out neighborhoods to retrieve their pets.

Maggie Shaarawi, vice president of the Animals Lebanon charity, is one of the rescuers.
