Family and friends mourn as Kochava Shriki, 44, who was killed in an attack in Bulgaria, is buried at a cemetery in Rishon Lezion, near Tel Aviv

Funerals have been held for the five Israelis killed in a suicide attack on a bus in Bulgaria on Wednesday.

The bodies of the victims - four men in their 20s and a pregnant woman - were flown to Tel Aviv on Thursday night, reports the BBC.

The Bulgarian bus driver and suspected suicide bomber also died in the attack, which targeted a bus carrying Israeli tourists at Burgas airport.

Bulgarian authorities have released CCTV footage of the man they suspect carried out the attack.

They say the man, who is white and believed to be around 36 years old, was carrying a fake US driving licence.

Israel blames Iran and the Lebanese Shia militant group Hezbollah for the blast in the eastern Bulgarian city, which also injured at least 30 people.

In response to Israel's accusations, an Iranian foreign ministry spokesman said on Thursday that Tehran strongly condemned "all terrorist acts".

Hezbollah has not publicly commented on the issue.
