The Bulgarian government said that Hezbollah was behind the bombing of a tourist bus in the country last year in which five Israelis were killed.
The findings will increase the pressure on the EU to designate the Lebanon-based militant group as a terrorist organisation.
The five Israelis were killed in the Black Sea town of Burgas last July when a bomb exploded on the bus that was transporting them to their hotel.
The driver of the bus, a Bulgarian, was also killed along with the bomber, and a further 32 Israelis were injured.
Despite the Israeli government immediately blaming Hezbollah and Iran for the attack, there was initial confusion when Bulgarian officials published CCTV footage of the supposed attacker, who appeared to be a westerner – he was carrying what turned out to be a fake Michigan state driver's licence, had long hair and was wearing shorts.
The conclusions of the Bulgarian investigation indicate that three people were involved in the attack and that the surviving individuals are Australian and Canadian. (© Independent News Service)
