Beirut CNN  — 

Israeli airstrikes in Lebanon have killed at least seven high-ranking Hezbollah commanders and officials in recent weeks, including the militant group’s chief Hassan Nasrallah, who was assassinated in a strike on his underground headquarters in Beirut on Friday.

The strikes have dealt the most significant blow to the Iran-backed militant group since its formation in the early 1980s.

Hezbollah has said it will choose a new chief soon. Meanwhile, Israel launched a ground offensive in southern Lebanon on Tuesday, marking the “next phase” of its war with Hezbollah.

As Hezbollah seeks to recuperate from the carnage and vows to continue fighting Israel, here’s a look at some of the group’s leaders who have been killed – and who remains.
