An unidentified injured Israeli tourist is carried in front of Borgas hospital after an explosion at Burgas airport, outside the Black Sea city of Burgas, Bulgaria, some 400 kilometers (250 miles) east of the capital, Sofia, Wednesday, July 18, 2012.
Ministry spokesman Lior Ben Dor said Thursday that six Israelis were killed and 32 were wounded. The Israeli media says the other two dead were Bulgarians.
The Israelis had just landed at the Black Sea city of Burgas on Wednesday when an explosion ripped through their bus.
Defense Minister Ehud Barak told Army Radio on Thursday he thought Lebanon's Iranian-sponsored Hezbollah group carried out the assault.
The bombing in Burgas was the latest in a string of attacks and attempted attacks attributed to Iran targeting Israelis and Jews overseas in the past year.
Iran has denied involvement for past attacks.
