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.

Israeli Defense Minister Yoav Gallant did say on Wednesday, however, that his country's war with Iran's so-called proxy groups in the region had entered a "new phase," announcing a shift to the north of Israel after 11 months of intense conflict with Hamas in the Gaza Strip.

The unprecedented attack, followed by explosions of walkie-talkies, comes after Israeli officials warned about escalating tensions on the Lebanese border.
