Foreign tourists wait to pass as police block the entrance of Burgas airport, Bulgaria, Thursday, July 19, 2012 a day after a deadly suicide attack on a bus full of Israeli vacationers. A daytime bombing that killed eight people and injured dozens on a bus full of Israeli tourists was most likely a suicide attack, Bulgaria's interior minister said Thursday. He said the suspected attacker was carrying a Michigan driver's license that was being sent to the FBI for authentication. (Associated Press)
