The Israeli military says it struck the central headquarters of Hezbollah in Beirut . The series of explosions Friday evening is the most powerful yet seen in the Lebanese capital the past year. The series of gigantic blasts at around nightfall reduced six buildings to rubble in the Haret Hreik neighborhood of Beirut’s Dahiyeh suburbs, according to Lebanon’s national news agency.

The shock wave rattled windows and shook houses some 30 kilometers (18 miles) north of Beirut. TV footage showed several craters — one with a car toppled into it — amid collapsed buildings in the densely populated, predominantly Shiite neighborhood. The Israeli army spokesman, Rear Adm.

Daniel Hagari, said it targeted the main Hezbollah headquarters, located beneath residential buildings. Prime Minister Benjamin Netanyahu abruptly cut short a visit to the United States and was returning home instead of waiting until the end of Sabbath on Saturday evening, his office said. Hours earlier, Netanyahu addressed the U.

N., vowing that Israel’s campaign against Hezbollah would continue — further dimming hopes for an internationally backed cease-fire . More than 720 people have been killed in Lebanon this week, according to Lebanon’s health ministry.

Israel has dramatically escalated strikes , saying it is targeting Hezbollah’s military capacities and senior Hezbollah commanders. Top Israeli officials have threatened to repeat the destruction of Gaza in Lebanon if the Hezbollah fire continues,.
