The suicide bomber who killed five Israelis was a foreign citizen, authorities in Sofia said on July 20, as Israel held funerals for the victims.
The burials, in different cities and towns around Israel, come after the five bodies were returned home by military transport overnight.
The attack on July 20 at Burgas airport killed the five Israelis, their Bulgarian bus driver, and the bomber.
More than 30 others were injured.
Israeli Prime Minister Benjamin Netanyahu has blamed Iran and Hizbollah for being behind the bombing.
Tehran and the Lebanese group have denied the accusation.
Video released by Bulgarian authorities shows the suspect, moments before the attack, walking in the airport with a backpack and with long hair and sunglasses.
Bulgarian Interior Minister Tsvetan Tsvetanov said the backpack contained the explosive device.
