Officials are scanning DNA samples from the fingers of the suicide bomber in the Bulgaria airport blast in a bid to identify him, the country's government has said.
Interior Minister Tsvetan Tsvetanov said video surveillance showed the attacker blended in among arriving Israeli tourists.
He looked like everybody else - a normal person with Bermuda shorts and a backpack.
Eight people, including the Bulgarian bus driver and the bomber, died in yesterday's blast at Burgas Airport.
Tsvetanov said Bulgarian security services had received no indications of a pending terrorist attack in the Balkan country.
