In a duplex in a quiet neighborhood of the Hungarian capital is the headquarters of a company that is linked to the manufacture of the pagers that exploded in Lebanon and Syria as part of an apparent Israeli operation against the Hezbollah militant group.

The Taiwanese company whose name appeared on the pagers that detonated across Lebanon has denied manufacturing the devices. That has put a lesser-known Budapest-based consulting firm in focus.

Hezbollah, the Lebanese militant group and political party, claimed that Israel was behind the security incident that struck its members. The New York Times also reported, citing U.S. and other officials, that Israel hid explosives in the batch of detonated pagers.
