The woman whose company was linked to thousands of pagers that exploded in Lebanon and Syria this week is under the protection of the Hungarian secret services, her mother told The Associated Press on Friday.

Cristiana Bársony-Arcidiacono has not appeared publicly since the deadly simultaneous attack that targeted Hezbollah on Tuesday and that has been widely blamed on Israel. She is listed as the CEO of Budapest-based BAC Consulting, which the Taiwanese trademark holder of the pagers said was responsible for the manufacture of the devices.
