"Hezbollah is an organization without a head. Nasrallah was eliminated, his replacement was probably also eliminated," Gallant told officers at the military's northern command centre, in a brief video segment distributed by the military. "There's no one to make decisions, no one to act," he said.

Hezbollah leader Hassan Nasrallah, who led the terror group for more than 30 years, was killed in an Israeli airstrike. Nasrallah, 64, was killed during a massive airstrike on the Iran-backed group's "central headquarters" in Beirut, Lebanon on Friday, the Israel Defense Forces said in a statement.
