Forensic experts search for evidence amid the debris on a street where a car bomb went off in Athens on April 10. The car bomb went off outside a Bank of Greece building in central Athens early on Thursday, smashing windows in nearby shops but causing no injuries, police and Reuters witnesses said. The blast struck hours before Greece planned its first foray into the international bond markets since it plunged into a debt crisis four years ago. Reuters/Alkis Konstantinidis
