Surveillance video of the man suspected of bombing a tourist bus at an airport in Bulgaria has been released as investigators attempt to identify him.
The footage shows a long-haired man carrying a large rucksack and a smaller carry-on bag, walking close to a Thomson stand at Burgas Airport.
Investigators are meanwhile scanning DNA samples from the fingers of the suspected bomber in a bid to trace his identity.
Officials said he was carrying a fake passport, which claimed he was travelling from the state of Michigan in the US.
