Relatives of five Israeli tourists killed in a bombing in Bulgaria have visited the site of the attack to light candles in memory of their loved ones.

The mourners walked Wednesday through the bus parking lot of the Burgas airport to the spot where on July 18 a still-unidentified suicide bomber detonated his explosives, killing the Israelis and a Bulgarian bus driver.

The families laid flowers at the site of the explosion and lit candles for the victims.

On Tuesday, the relatives attended a ceremony in the country's biggest synagogue, where they were joined by Bulgarian President Rosen Plevneliev and Israeli Vice Prime Minister Moshe Yaalon.
