Lebanon's Hezbollah was still handing its members new Gold Apollo branded pagers hours before thousands blew up this week, two security sources said, indicating the group was confident the devices were safe despite an ongoing sweep of electronic kit to identify threats.

Hezbollah admits Israel dealt a severe blow with exploding pagers and walkie talkies, but neither side seems to heed U.S. calls to avoid a wider war.

Hezbollah and Israel have traded blows in recent days, as the conflict has escalated with few off-ramps in sight to avoid total war.
