"Out of thousands of people, we need to find four or five," Bulgarian Interior Minister Tsvetan Tsvetanov said on Friday in reference to the police investigation into the terror attack
that killed five Israeli tourists and a Bulgarian bus driver in the resort city of Burgas.
In an interview with Bulgarian news website Novinite, Tsvetanov estimated that "the probe might take years."
Bulgarian minister noted that they were not able to establish a claim made by two Israeli witnesses, by which the explosive device was hidden in the luggage compartment of the bus that was transferring Israeli tourists to their hotels. He added that the investigation indicates that a country or terror organization were behind the attack, but refused to name any suspects.
Immediately after the attack, Prime Minister Benjamin Netanyahu
saying "it's time that all the world's countries speak the truth clearly and say that Iran is behind the wave of terror."
On Thursday, Bulgarian authorities released
a computer-generated image of a suspected accomplice of the suicide bomber. The image of a man with short dark hair was accompanied by a photo from a fake driver's license, in which the man appears to be wearing a wig.
