Israel says it struck Hezbollah’s headquarters as huge explosions rocked Beirut

The Israeli military said Friday it carried out an airstrike on the central headquarters of Hezbollah in Beirut, where a massive explosion leveled buildings in a southern district, sending clouds of orange and black smoke billowing in the skies.

The strike in the Beirut suburb of Dahiyeh came shortly after Israeli Prime Minister Benjamin Netanyahu addressed the U.N., vowing that Israel's campaign against Hezbollah would continue. Not long before the explosion, thousands were massed in the suburb for the funeral of three Hezbollah members, including a senior commander, killed in earlier strikes.

There was no immediate word on casualties in the strike. The Israeli army spokesman, Rear Adm. Daniel Hagari, said it targeted the main Hezbollah headquarters, located beneath residential buildings. Hezbollah's Al-Manar TV said four buildings were reduced to rubble in the blast, so powerful it rattled windows and shook houses some 30 kilometers north of Beirut. Ambulances were seen headed to the scene of the explosions, sirens wailing.

Earlier in the day, an Israeli airstrike killed a family of nine in a Lebanese border village, authorities said, as Lebanon struggled to deal with a rising death toll, a wave of tens of thousands fleeing their homes and the possibility of an all-out war between Israel and Hezbollah.

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 scope of Israel's operation remains unclear, but officials have said a ground invasion to push the militant group away from the border is a possibility. Israel has moved thousands of troops toward the border in preparation.
