The Israeli army on Friday evening carried out a heavy and unprecedented airstrike on Beirut's southern suburb area, claiming to have attacked the main headquarters of Lebanese group Hezbollah.

According to an Anadolu correspondent on the ground, Israeli warplanes launched some 10 airstrikes on the area, which is a Hezbollah stronghold, with a large smoke plume rising over the area.

Shortly after the airstrikes, Israeli army spokesman Daniel Hagari said the attack targeted Hezbollah's main headquarters, which he claimed was built underneath civilian buildings.

According to Israeli Channel 12, the Israeli army is verifying whether Hezbollah chief Hassan Nasrallah was inside the targeted area.

Meanwhile, Israeli public broadcaster KAN suggested that Nasrallah may have been inside a tunnel struck by the Israeli jets.

Lebanon's official news agency NNA reported extensive damage in the Harat Hreik area of southern Beirut, with several buildings collapsing and thick clouds of smoke rising from the area.

In response to the attack, the Lebanese Red Cross announced on X that they had deployed 10 teams to the scene.
