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.

BAC Consulting shares the ground floor of the modest building in Budapest with other enterprises. On Wednesday morning, Associated Press journalists saw the names of multiple companies, including BAC, posted on pieces of printer paper and taped in a window.

In a corporate registry, the company listed 118 official functions, including sugar and oil production, retail jewelry sales and natural gas extraction.

BAC reportedly supplied the thousands of devices that killed at least 12 people, including two children, and wounded about 2,800 on Tuesday in a coordinated attack that Hezbollah and the Lebanese government blamed on Israel.
