Batteries of Lebanon walkie-talkies contained PETN explosive

BEIRUT (Reuters) -The batteries of the walkie-talkies used by Lebanese armed group Hezbollah that blew up this week were laced with a highly explosive compound known as PETN, a Lebanese source familiar with the device's components told Reuters. The way the explosive material was integrated into the battery pack made it extremely difficult to detect, the source said. Pictures of the walkie-talkies that had exploded showed labels reading "ICOM" and "made in Japan".
