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.

Walkie-talkies and solar equipment exploded in Beirut and other parts of Lebanon on Wednesday in an apparent second wave of attacks targeting devices a day after pagers used by Hezbollah blew up, state media and officials for the militant group said.
