Components used in thousands of pagers that detonated in Lebanon were not made in Taiwan, Taiwan’s economy minister has said, Reuters reports.

Taiwan-based Gold Apollo said this week it did not manufacture the devices used in the attack, and that Budapest-based company BAC to which the pagers were traced has a license to use its brand.

“The components are (mainly) low-end IC (integrated circuits) and batteries,” Taiwan’s Economy Minister Kuo Jyh-huei told reporters.

When he was pressed on whether the parts in the pagers that exploded were made in Taiwan, he said, “I can say with certainty they were not made in Taiwan,” adding the case is being investigated by judicial authorities.

Taiwan’s Foreign Minister Lin Chia-lung, also speaking to reporters at parliament, answered “no” when asked if he had met with the de facto Israeli ambassador to express concern about the case.
