Bulgarian chief prosecutor says a new suspect has been identified in 2012 bus bombing

SOFIA, Bulgaria – Bulgaria's chief prosecutor says investigators have identified a fourth person they think was involved in the July 2012 bomb attack that killed five Israeli tourists and their Bulgarian bus driver.

Sotir Tsatsarov told reporters Thursday that because of the new evidence, the indictment will be delayed. He did not elaborate on the identity or the nationality of the new alleged accomplice.

Bulgaria has already identified two of the suspects as 32-year-old Meliad Farah of Australia, also known as Hussein Hussein, and 25-year-old Hassan El Hajj Hassan, a Canadian citizen. Both are of Lebanese origin.

The suicide bomber who died on the spot in the bombing at Burgas Airport on the Black Sea coast has not been identified.
