BEIRUT — A rare Israeli strike in central Beirut killed the Hezbollah militant group’s chief spokesperson on Sunday, while an Israeli strike in northern Gaza’s Beit Lahiya killed at least 30 people, a hospital director there told The Associated Press.

Mohammed Afif al-Naboulsi was killed in a strike on the Arab socialist Baath party’s office in Beirut, Hezbollah confirmed in a statement. He had been especially visible after all-out war erupted between Israel and Hezbollah in September.

Israel’s military in a statement said he “wielded significant influence over Hezbollah’s military operations” and “glorified and incited” attacks on Israel.

It was the latest targeted killing of a senior Hezbollah official. On Sunday night, another strike in central Beirut hit a computer shop, killing two people and wounding 22, Lebanon’s Health Ministry said. There was no immediate comment from Israel’s military.

The strikes happened as Lebanese officials considered a United States-led cease-fire proposal. “This confirms the crimes of the Israeli enemy, and that it wants to negotiate under fire and is expanding and targeting safe and safer areas,” said a Lebanese member of parliament, Faisal Al Sayegh.

Israel also bombed several buildings in Beirut’s southern suburbs, where Hezbollah has long been headquartered, after warning people to evacuate.

There was no Israeli evacuation warning before the strike near a busy intersection that killed Afif. Four people were killed and 14 wounded including two children, the Health Ministry said.

“I was asleep and awoke from the sound of the strike, and people screaming, and cars and gunfire,” said witness Suheil Halabi.

After the second strike in central Beirut, firefighters struggled to control the blaze in the busy residential neighborhood of Mar Elias. Bystanders said they heard a second explosion and a car nearby appeared to be hit.

On Sunday, Israel’s military said mobile artillery batteries had crossed into Lebanon and began attacking Hezbollah targets, the first time artillery was launched within Lebanese territory.

Lebanon’s army, largely on the sidelines, said an Israeli strike on Sunday hit a military center in southeastern Al-Mari, killing two soldiers and wounding two others. There was no immediate Israeli comment.

The director of the Kamal Adwan hospital in Beit Lahiya, Hosam Abu Safiya, said dozens were wounded in the Israeli strike and other people likely were under the rubble.

Fleeing residents told the AP that houses were hit. An Israeli military statement earlier said it conducted several strikes on “terrorist targets” in Beit Lahiya, and that efforts to evacuate civilians from the “active war zone” continued.

Israeli forces have again been on the offensive in northern Gaza, saying Hamas militants have regrouped.

“Tonight we did not sleep at all,” said one fleeing Beit Lahiya resident, Dalal al-Bakri. “They destroyed all the houses around us. ... There are many martyrs.”

A woman, Umm Hamza, said the bombing escalated overnight. “It’s cold and we don’t know where to go,” she said.

Earlier, officials said Israeli strikes killed six people in Nuseirat and four in Bureij, two built-up refugee camps in central Gaza dating back to the 1948 war surrounding Israel’s creation.

Two people were killed in a strike on Gaza’s main north-south highway, according to Al-Aqsa Martyrs Hospital in the central city of Deir al-Balah.

Israel’s military said two soldiers were killed in northern Gaza on Sunday.

The war between Israel and Hamas began after Palestinian militants stormed into Israel on Oct. 7. last year. Around 100 hostages remain in Gaza, about a third believed to be dead.

On Sunday, Israel’s Shin Bet internal security agency said it met with the heads of the army and intelligence to discuss mediation efforts to release the hostages. It was the first public word of any such effort since Qatar announced earlier this month it was suspending its mediation work.
