BEIRUT — Hezbollah’s newly named leader Naim Kassem said in his first public comments aired Wednesday that the militant group will keep fighting in its ongoing war with Israel until it is offered cease-fire terms it deems acceptable.

“If the Israelis decide to stop the aggression, we say that we accept, but according to the conditions that we see as suitable,” Kassem said, speaking from an undisclosed location in a pre-recorded televised address. “We will not beg for a cease-fire as we will continue (fighting) ... no matter how long it takes.”

The speech came as international mediators have launched a new push for negotiated cease-fires in Lebanon and Gaza.

According to two officials briefed on the negotiations who spoke on the condition of anonymity to discuss sensitive diplomacy, Israel is pushing for an arrangement in which Hezbollah would be given several weeks to withdraw forces from the Israel-Lebanon border, allowing Lebanon’s official army, now sidelined by Hezbollah in southern Lebanon for over two decades, to fill the void, according to two of the officials.

Israel also wants to be guaranteed the right to invade Lebanon if Hezbollah doesn’t withdraw fast enough, the officials said.

More than 2,790 people have been killed and 12,700 wounded in Lebanon since Oct. 8, 2023, when Hezbollah began firing rockets into Israel, according to Lebanon’s Health Ministry. The conflict escalated sharply last month, and Israeli ground forces invaded southern Lebanon at the beginning of October. Some 1.2 million people have been displaced by the conflict in Lebanon, according to government estimates.

In Israel, rockets, missiles and drones launched by Hezbollah have killed at least 63 people, about half of them soldiers. More than 60,000 Israelis from towns and cities along the border have been evacuated from their homes for over a year.

Kassem, a cleric and founding member of the Iran-backed militant group, was named Tuesday to replace former longtime leader Hassan Nasrallah, who was killed in an Israeli airstrike on a Beirut suburb in late September. Kassem was Nasrallah’s deputy for more than three decades.

Several other high-ranking officials with the group, including Nasrallah’s presumptive successor, Hashem Safieddine, also were killed in recent weeks, as the Israel-Hezbollah war has escalated in Lebanon.

Kassem said the series of blows dealt to the group in recent weeks — including pager and walkie-talkie explosions that targeted Hezbollah members in mid-September and the assassination of Nasrallah — had “hurt” the group, but he asserted that Hezbollah had been able to reorganize its ranks within eight days after Nasrallah’s death.

“Hezbollah’s capabilities are still available and compatible with a long war,” he said. He pointed to the steady stream of Israeli soldiers wounded and killed in southern Lebanon since Israeli forces launched a ground invasion on Oct. 1, and to a drone launched by Hezbollah that hit the home of Israeli Prime Minister Benjamin Netanyahu earlier this month. Netanyahu was not harmed.

He said Hezbollah has been in coordination with Lebanese Parliament Speaker Nabih Berri, the primary Lebanese official communicating with the United States, which has put forward a series of proposals to end the conflict.

“So far no project has been put forward that Israel agrees on and is acceptable for us to negotiate it,” Kassem said.

Kassem said Hezbollah is carrying out plans laid out by its slain former chief in the ongoing war.

There was no immediate Israeli response to the speech, though several Israeli leaders have hinted that Kassem is Israel’s next high-level assassination target. On Tuesday, Defense Minister Yoav Gallant tweeted a photo of Kassem with the words “Temporary appointment. Not for long.” Foreign Minister Israel Katz said Israel would “ensure” that Kassem follows in Nasrallah’s footsteps.

As Kassem was speaking, a series of Israeli airstrikes pounded the eastern city of Baalbek.

The Israeli army had earlier issued an evacuation warning for residents in the entire eastern Lebanese city of Baalbek, including the ancient Roman temple complex, a UNESCO World Heritage site.

The army said they were targeting fuel depots to halt the movement of weapons and artillery from Iran. U.S. State Department spokesperson Matthew Miller said Israel has a responsibility to protect civilian infrastructure and heritage sites.

On Oct. 6, an Israeli strike hit about 750 yards from the ancient citadel, which houses two of the largest Roman temples in the world.
