Israel’s assassination of Hassan Nasrallah, the long-standing leader of Hezbollah, represented a major escalation in its war with the Lebanese militant group. With the region on the brink of a widening conflict, we look at how Israel's attacks on Hezbollah's leadership have potentially weakened the organisation, and what that could mean for the course of the war. Host Katya Adler asks the BBC's security correspondent Frank Gardner how the conflict between Hezbollah and Israel escalated and what each actor might do next.
