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

"The components for Hezbollah's pagers were not produced by us," Taiwan's economy minister Kuo Jyh-huei told reporters on Friday. He added that a judicial investigation is already under way. "I want to unearth the truth, because Taiwan has never exported this particular pager model," Taiwan foreign minister, Lin Chia-lung said.

Two people from Taiwanese companies were questioned as part of a probe into pagers that exploded while being used by Hezbollah operatives in Lebanon, investigators said Friday, as top officials insisted the devices were not from the island.
