Israel’s recent elimination of Hezbollah’s longtime leader Hassan Nasrallah has left the Iranian-backed terror group reeling and searching for a successor.

Nasrallah, who had led Hezbollah’s campaign of violence against Israel and Western interests for over three decades, was killed Friday evening when Israeli forces leveled his Beirut hideout. His death marks a crippling blow to the organization, which has already seen much of its leadership decimated by months of targeted Israeli operations.

According to Al Jazeera, two frontrunners have emerged in the race to take over the reins of the Iranian-backed terror outfit.

Hashem Safieddine, Nasrallah’s cousin and head of Hezbollah’s executive council, is widely seen as the heir apparent. His prominence in orchestrating attacks against Western interests has earned him a place on both US and Saudi terror lists. Safieddine studied theology alongside Nasrallah in Iran and Iraq before helping found Hezbollah. His tentacles reach deep into Hezbollah’s terror apparatus, with key positions on the group’s executive council, Shura Council, and Jihadi Council.

With a family connection to slain Iranian general Qassem Soleimani, the 60-year-old hardliner would make a natural fit to continue Nasrallah’s legacy of terror.

Naim Qassem, Hezbollah’s 71-year-old deputy leader, is the other leading contender. A veteran of Lebanon’s Shiite political scene, Qassem helped establish Hezbollah in the 1980s and has been Nasrallah’s right-hand man for decades. He’s taken on a more public-facing role in recent years, even penning a book in 2005 on the inner workings of the terror group titled “The Story from Within.”
