Hezbollah chief killed in Israeli strikes: What next for Lebanon and who will succeed Hassan Nasrallah?

Hezbollah chief Hassan Nasrallah was killed on Friday as Israel launched a barrage of air strikes towards Lebanon. The development comes days after Tel Aviv shifted the focus of its ongoing operation from Gaza to Lebanon. The attack has also put the spotlight on Hashem Safieddine — widely regarded as the heir to Nasrallah. Choosing a successor will be a complicated process for the militant group — especially in the wake of multiple Israeli attacks that have killed top commanders and raised questions about internal security. Any new leader will also have to be acceptable within the organisation in Lebanon as well as its backers in Iran.
