The senior Lebanese security source said the group had ordered 5,000 beepers made by Taiwan-based Gold Apollo, which several sources say were brought into the country earlier this year.
Israel's Mossad spy agency planted a small amount of explosives inside 5,000 Taiwan-made pagers ordered by Lebanese group Hezbollah months before Tuesday's detonations, a senior Lebanese security source and another source told Reuters.
But the senior Lebanese source said the devices had been modified by Israel's spy service "at the production level."
Another security source told Reuters that up to three grams of explosives were hidden in the new pagers and had gone "undetected" by Hezbollah for months.
"We really got hit hard," said the senior Lebanese security source, who has direct knowledge of the group's probe into the explosions.
