Prime Minister Benjamin Netanyahu said today that Israel had killed Hezbollah's new secretary general and the man who replaced Hassan Nasrallah after he was assassinated in an airstrike in September.

Prime Minister Benjamin Netanyahu said on Tuesday Israeli airstrikes had killed two successors to Hezbollah's slain leader, as Israel expanded its ground offensive against the Iran-backed group with a fourth army division deployed into south Lebanon.

The Israeli army said on Thursday that it had launched attacks overnight on targets in the suburbs of Beirut, hitting ammunition depots in areas considered Hezbollah strongholds, and that two of the militant group's commanders were killed in southern Lebanon.

Israel’s military said Thursday it carried out airstrikes that killed two Hezbollah commanders who were involved in missile attacks targeting northern Israel. The Israel Defense Forces identified the commanders as Ahmad Moustafa al-Haj Ali and Mohammad Ali Hamdan.
