Cristiana Bársony-Arcidiacono has not appeared publicly since the deadly attack that targeted Iran-backed Hezbollah and that has been widely blamed on Israel.

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.

The trail of the pagers that blew up in Lebanon around 3:30 p.m. Tuesday, killing or maiming thousands and sparking fears of a new Middle East war, leads to a small post-box office wedged between a highway and a dilapidated railway station in Budapest.
