Hassan Nasrallah, who has been assassinated by Israel aged 64, was a Lebanese cleric and the Secretary-General of Hezbollah (“Party of God”), the Shia militant group which forms part of the Lebanese government.

Israel said Saturday that it killed Hezbollah leader Hassan Nasrallah, dealing its most significant blow to the Lebanese militant group after months of fighting. There was no immediate confirmation from Hezbollah.

In 32 years in charge of Hezbollah, Mr. Nasrallah built the Iranian-backed militia into an influential regional force and a potent adversary of Israel.
