Bulgaria's Interior Minister Tsvetan Tsvetanov said Thursday the identity of the suspect responsible for the suicide bombing that killed eight people and injured dozens on a bus full of Israeli tourists Wednesday in the eastern Bulgarian city of Burgas is unknown. He said the suspected attacker was carrying a driver's license issued in Michigan, that was later found to be false and accordingly the suspect's identity remains anonymous. "We worked on this with colleagues from the FBI and CIA. They said that there is no such person in their database," Bulgarian Prime Minister Boyko Borisov said today. Boyko condemned the violent incident, stressing that Bulgaria will do everything in its power to find the perpetrators of the attack and bring them to justice.
