BEIRUT: Israel said it had struck Hizbollah's intelligence headquarters in the Lebanese capital Beirut on Sunday, while officials in Gaza said they were still trying to recover bodies from the rubble after an Israeli strike that killed dozens.

At least 87 people were dead or missing following the airstrike on Beit Lahia in northern Gaza late on Saturday, the health ministry in the Palestinian territory said, one of the highest death tolls reported for months from a single attack. Israel said it was investigating reports of the incident.

It marked an intensification of Israel's offensives against Palestinian group Hamas in Gaza and Iran-backed Hizbollah in Lebanon, days after the killing of Hamas leader Yahya Sinwar had raised hopes of an opening for ceasefire negotiations to end more than a year of escalating conflict in the Middle East.

With US elections approaching, officials, diplomats and other sources in the region say Israel is seeking through military operations to try to shield its borders and ensure its rivals cannot regroup.

Israel is also preparing to retaliate for an Iranian missile barrage earlier this month, though Washington has pressed it not to strike Iranian energy facilities or nuclear sites.

Prime Minister Benjamin Netanyahu said he was the subject of an assassination attempt by "Iran's proxy Hizbollah" on Saturday when a drone was directed at his holiday home. In a call with former US President Donald Trump, the prime minister reiterated that Israel would make decisions based on its own interests, according to a statement from Netanyahu's office.

Israel's government has rejected several attempts by the United States, its main ally and military backer, at brokering ceasefires in both Gaza and Lebanon.

EVACUATION ORDERS

In Gaza, the health ministry said rescue operations following the strike in Beit Lahia were being hindered by communications problems and by ongoing Israeli military operations.

The strike came two weeks into a major assault around the town of Jabalia, just to the south of Beit Lahia, where Israeli troops backed by tanks have been trying to root out remaining Hamas fighters.

Israel said the strike hit a Hamas target, questioning an earlier death toll of 73 released by the Hamas media office.

Over 5,000 Palestinians left Jabalia via designated routes, Israeli military spokesperson Avichay Adraee said on social media platform X.

Evacuation orders directing people south have fuelled fears among many Palestinians that the operation is intended to clear them out of the northern part of Gaza to help ensure Israeli control of the area after the war.

Israel has denied any such plans, saying it is trying to protect civilians and separate them from Hamas fighters.

The Israeli offensive, triggered by the Oct. 7, 2023 Hamas attack on Israel, has made most of Gaza's 2.3 million people homeless, caused widespread hunger and destroyed hospitals and schools.

"Horrifying scenes unfolding in Gaza, amidst conflict, relentless Israeli strikes & an ever-worsening humanitarian crisis," UN Middle East peace envoy Tor Wennesland posted on X.

BEIRUT STRIKES

In Lebanon, Israel stepped up its bombardment of southern Beirut from Saturday afternoon. On Sunday, it said its air force attacked Hizbollah's intelligence headquarters in Beirut as well as an underground workshop for the production of weapons.

Fighter jets killed three Hizbollah commanders, including Alhaj Abbas Salameh, a senior figure in the group's southern command, the Israeli military said in a statement.

Reuters witnesses saw smoke rising from Beirut's southern suburbs, once a densely populated zone that also housed Hizbollah offices and underground installations.

The Lebanese military said on Sunday three of its soldiers were killed in an Israeli strike on an army vehicle in southern Lebanon.

Hizbollah made no immediate comment on the strikes, but said it had fired missiles at Israeli forces in Lebanon and at a base in northern Israel.

Cross-border fighting between Israel and Hizbollah erupted a year ago when the Iranian-backed group began launching rockets in support of Hamas.

At the start of October, Israel launched a ground assault inside Lebanon in an attempt to stabilise the border region for its citizens who had fled rocket attacks in northern Israel.

Over the last year, more than 2,400 people have been killed, according to Lebanon's health ministry, with more than 1.2 million people displaced, most in recent weeks. Fifty nine people have been killed in northern Israel and the occupied Golan Heights over the same period, say Israeli authorities.

Hamas-led fighters killed some 1,200 people and took 250 hostages in the attack that sparked the war, according to Israeli tallies. Israel's military response in Gaza has left more than 42,500 people dead, Palestinian officials say.
