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

The president and founder of a Taiwanese pager company linked to the detonation of thousands of pagers targeting Hezbollah in Lebanon was questioned by prosecutors late into the night on Thursday, then released.

Israel’s operation against Hezbollah members in Lebanon and Syria through booby-trapped pagers and walkie-talkies was years in the making, and its use now ramped up a high-risk campaign aimed at deeply disrupting the group.

The Israeli military said it carried out a "targeted strike" in the Lebanese capital Beirut on Friday. The strike comes amid growing fears the war in Gaza could expand into a larger conflict. DW has more.
