Police have released CCTV footage of the man suspected of carrying out a suicide bombing which killed seven people in Bulgaria.

The group of tourists had arrived in Bulgaria on a charter flight from Israel and were on the bus in the airport car park when the blast tore through the vehicle.

Body parts were strewn across the ground, mangled metal hung from the double-decker bus's ripped roof and black smoke billowed over the airport.

Video of the suspect shows him wearing a blue T-shirt and black rucksack whilst walking through the airport terminal.

He is said to be 36-years-old and had been in the country for between four and seven days before the attack.
