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.

The pagers, deemed by Hezbollah to be safer than cellphones, were probably rigged with explosives before they were delivered to Lebanon, experts said.

"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 underway. "I want to unearth the truth, because Taiwan has never exported this particular pager model," Taiwan foreign minister, Lin Chia-lung said.
