(FOX NEWS) The suspected suicide bomber in Wednesday’s attack on a tour bus that killed seven and injured dozens was carrying a fake U.S. identification card, the Bulgarian prime minister said.

The suspect, whose nationality has not been determined, had a fake Michigan license, Prime Minister Boiko Borisov said in an interview. Six of the victims on the tour bus are Israeli citizens.

The explosion gutted the bus at the Burgas airport, which is frequented by tourists visiting the Black Sea. The suspected bomber, who was 36 years old and wore Bermuda shorts, appeared on a security camera for nearly an hour before the attack, Tsvetan Tsvetanov, Bulgaria’s interior minister said.
