Taiwan-based Gold Apollo said the devices were made by a Budapest-based company with a license to use its brand.

The deadly simultaneous explosions triggered by hundreds of pagers carried by Hezbollah members in Lebanon have thrust a little-known Taiwanese electronics manufacturer into the global spotlight, after its damaged products were identified in images following the attack.

Caught in the crisis, Taiwanese firm Gold Apollo's founder Hsu Ching-Kuang flatly denied his company had anything to do with the attacks. Instead, Mr Hsu has said he licensed his trade mark to a company in Hungary called BAC Consulting to use the Gold Apollo name on their own pagers. BBC attempts to contact BAC have so far been unsuccessful.
