Who is Hashem Safieddine, the cleric likely to head Hezbollah after Nasarallah's death

Analysts told news agency AP that Nasrallah's assassination is a significant setback for the force as it revealed the extent of its vulnerability against its arch enemy Israel.

“This will shake the confidence of Hezbollah’s Iran-backed allies across the Arab world, from the Houthis in Yemen to the Popular Mobilization Forces in Iraq, as well as Iran itself, sparking a tectonic shift in Iran’s network of influence in the Middle East,” said Lina Khatib, an associate fellow at Chatham House, an international affairs think tank.

As Hezbollah contemplates its next response to Israel, analysts say the group lacks a leader as influential as Nasrallah to command widespread acceptance among other leaders within its force.
