A bombing on a bus with Israeli tourists in Bulgaria was likely carried out by a suicide attacker, the nation's interior minister said Thursday.

The attack occurred Wednesday in a parking lot outside Burgas Airport in Bulgaria.

"From what we could see on the video cameras ... we identified a person who served as a suicide bomber in this terror attack," Interior Minister Tsvetan Tsvetanov told Bulgarian National TV.

Another person died from the blast overnight, he said, bringing the death toll to eight. The dead are six Israelis, a Bulgarian bus driver and the suicide bomber.

Thirty-two people remain hospitalized.
