This image taken from CCTV provided by the Bulgarian Interior Ministry who claim it shows the unidentified bomber, centre, with long hair and wearing a baseball cap, at Burgas Airport on Wednesday, July 18, 2012. The brazen daytime bombing that killed seven people and injured dozens on a bus full of Israeli tourists was most likely a suicide attack, Bulgarian officials said Thursday. Israel stood by its claim that Iranian-backed Hezbollah was responsible and vowed to hit back. The identity of the suspected bomber was still unknown but a Michigan driving license that he carried was a fake, Bulgarian Prime Minister Boiko Borisov said.
