By Laila Bassam and Maya Gebeily BEIRUT (Reuters) -Hand-held radios used by armed group Hezbollah detonated on Wednesday across Lebanon's south in the country's deadliest day since cross-border fighting erupted between the militants and Israel nearly a year ago,

Hezbollah officials and Lebanon's state media say explosions went off in Beirut and multiple parts of Lebanon in an apparent second wave of detonations of electronic devices. The officials and state media said Wednesday that walkie-talkies and even solar equipment detonated a day after hundreds of pagers blew up.
