The Bulgarian government has released CCTV images of a man suspected of targeting Israeli tourists in a bus bomb attack.

At least seven people were killed and 30 injured in the explosion outside the airport in the Black Sea resort of Burgas.

Bulgarian officials say the attack was probably carried out by a male suicide bomber with fake US documents.

The BBC's Kirsty Lang reports.
