BEIRUT — The Israeli military struck Hezbollah's headquarters in Beirut on Friday in a series of massive explosions that targeted the leader of the militant group and leveled multiple high-rise apartment buildings.

The biggest blast to hit the Lebanese capital in the past year appeared likely to push the escalating conflict closer to full-scale war. At least six people were killed and dozens were wounded, Lebanon's health ministry said.

Hezbollah leader Hassan Nasrallah was the target of the strikes on the group's headquarters, according to two people familiar with the matter who requested anonymity, including one U.S. official. The Israeli army declined to comment on who it targeted. It was not immediately clear if Nasrallah was at the site, and Hezbollah did not comment on the report.

After the strikes, Prime Minister Benjamin Netanyahu abruptly cut short a visit to the United States to return home. Hours earlier, he addressed the U.N., vowing that Israel's intensified campaign against Hezbollah over the past two weeks would continue — further dimming hopes for an internationally backed cease-fire.

“Israel has every right to remove this threat and return our citizens to their home safely. And that’s exactly what we’re doing,” Netanyahu said, eliciting applause from supporters in the gallery of the General Assembly. “We’ll continue degrading Hezbollah until all our objectives are met."

When Netanyahu entered the hall and was introduced, boos and raised voices echoed, and many delegates walked out. 

News of the blasts came as Netanyahu briefed reporters after his U.N. address. A military aide whispered into his ear, and Netanyahu quickly ended the briefing.

Israeli army spokesman Rear Adm. Daniel Hagari said the strikes targeted the main Hezbollah headquarters, saying it was located underground beneath residential buildings.

Rescuers arrive at the site of an Israeli airstrike Friday in Beirut's southern suburbs.

The series of blasts around nightfall reduced six apartment towers to rubble in Haret Hreik, a densely populated, predominantly Shiite district of Beirut's Dahiyeh suburbs, according to Lebanon's national news agency. A wall of billowing black and orange smoke rose into the sky as windows were rattled and houses shaken some 18 miles north of Beirut.

The Health Ministry reported at least six people killed and 91 others wounded but said the figure was likely to rise as first responders were still searching under the rubble.

Footage showed rescue workers clambering over large slabs of concrete, surrounded by high piles of twisted metal and wreckage. Several craters were visible, one with a car toppled into it. A stream of residents carrying their belongings were seen fleeing along a main road out of the district.

To a degree unseen in past conflicts, Israel this week has aimed to eliminate Hezbollah's senior leadership. But an attempt to assassinate Nasrallah — successful or not — would be a major escalation. The Pentagon said the U.S. had no advance warning of the strikes.

Nasrallah has been in hiding for years, very rarely appearing in public. He regularly gives speeches, but always by video from unknown locations.

The site hit Friday evening had not been publicly known as Hezbollah's main headquarters, though it is located in the group's "security quarters," a heavily guarded part of Haret Hreik where it has offices and runs several nearby hospitals.

Israel dramatically intensified its airstrikes in Lebanon this week, saying it is determined to put an end to more than 11 months of Hezbollah fire into its territory. The escalated campaign has killed more than 720 people in Lebanon, including dozens of women and children, according to Health Ministry statistics.

Iranian-backed Hezbollah, the strongest armed force in Lebanon, began firing rockets into Israel almost immediately after Hamas' Oct. 7 attack, saying it was a show of support for the Palestinians. Since then, it and the Israeli military traded fire almost daily, forcing tens of thousands of people to flee their homes on both sides of the border.

Mourners bury the bodies of their relatives Friday who were killed in Israeli airstrikes in the village of Karak, eastern Lebanon.

Hezbollah officials and their supporters remain defiant. Not long before the explosions Friday evening, thousands massed in another part of Beirut's suburbs for the funeral of three Hezbollah members killed in earlier strikes, including the head of the group's drone unit, Mohammed Surour.

Men and women in the giant crowd waved their fists in the air and chanted, "We will never accept humiliation" as they marched marched behind the three coffins, wrapped in the group's yellow flag.

Hussein Fadlallah, Hezbollah's top official in Beirut, said in a speech that no matter how many commanders Israel kills, the group has endless numbers of experienced fighters. He vowed that Hezbollah will keep fighting until Israel stops its offensive in Gaza.

"We will not abandon the support of Palestine, Jerusalem and oppressed Gaza," Fadlallah said. "There is no place for neutrality in this battle."
