The Bulgarian government is planning to indict two Lebanese men suspected of carrying out the Burgas terror bombing last year and try them in absentia if they are not extradited.

Six people were killed in the suicide attack that took place on a tourist bus in the resort of Burgas in July 2012; five of them were Israelis.

Despite express denials, Israeli and Western intelligence agencies believe that the attack was masterminded by the military wing of Hizbollah.

The two suspects, Maiad Farah and Haj Hassan, are Lebanese citizens but carried Australian and Canadian passports. They are believed to be Hizbollah members. According to the investigators, they prepared the bomb and helped the suicide bomber reach his target. Following the attack they fled the country and are now believed to be living in Lebanon.

Prosecutor Sutir Tzartzarov said at a press conference on Friday: “Bulgaria must send a clear signal of zero-tolerance of terrorism… Our aim is to indict them in the first three months of next year after we have collected enough material to prove their guilt.”

Earlier this year, the EU voted to recognise Hizbollah’s military wing as a terror organisation.
