Components used in thousands of pagers that detonated on Tuesday in Lebanon were not made in Taiwan, Taiwan's economy minister said on Friday.

The pagers, traced back to Budapest-based BAC Consulting, carried branding from Taiwan’s Gold Apollo, which denies manufacturing the devices. Taiwan’s Economy Minister, Kuo Jyh-huei, emphasized, “I can say with certainty they were not made in Taiwan,” and noted that the incident is under investigation by Taiwanese judicial authorities.

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.
