Bulgaria has identified a Lebanese man as the bomber who blew up an airport bus in 2012, killing five Israeli tourists, their Bulgarian driver and himself, local media said Sunday.

Israel and Bulgaria have already accused Hizbullah of being behind the attack at Burgas airport on the Black Sea, the deadliest on Israelis abroad since 2004.

Bulgaria's chief prosecutor says investigators have identified a fourth person they think was involved in the July 2012 bomb attack that killed five Israeli tourists and their Bulgarian bus driver.

Sotir Tsatsarov told reporters Thursday that because of the new evidence, the indictment will be delayed.

Bulgaria aims to open a trial by April for a bomb attack that killed five Israeli tourists at an airport last year, the chief prosecutor said Thursday.

"Our ambition is to go to court... by the end of the first three months of next year at the maximum," Sotir Tsatsarov told journalists.

Bulgarian investigators on Friday re-enacted a July 2012 bomb attack blamed by Sofia on Hizbullah that killed five Israelis, blowing up two old buses and 11 silicon mannequins in a controlled explosion.

The aim was "to provide information and important evidence on the type and quantity of explosive used" in the attack at Burgas airport on the Black Sea, chief investigator Boyko Naydenov said.

The Bulgarian Charge d'Affaires in Lebanon, Plamen Tzolov, said his government was still waiting for the cooperation of the Lebanese authorities on the investigation into the bus bombing on Israeli tourists last year.

In remarks to As Safir daily published Thursday, Tzolov said: “The Bulgarian government is still waiting for the response of the Lebanese government and mainly the justice ministry on a request made by Bulgaria to cooperate on this security file.”

France does not rule out the possibility of labeling Hizbullah as a terrorist organization in light of Bulgaria's accusation against it of being involved in the 2012 Burgas bus attack, reported An Nahar daily Saturday.

French Foreign Ministry Spokesman Philippe Lalliot said that the European Union may discuss this issue should one of the EU ministers make such a proposal, said the daily.

Expectations are rising that Bulgarian officials will confirm on Tuesday a link between Hizbullah and a suicide attack in Bulgaria that left five Israeli tourists dead in July last year, the New York Times reported.

A spokesman for the Bulgarian president’s office, Veselin Ninov, said that Interior Minister Tsvetan Tsvetanov, was expected to “announce the results of the interim progress report in the investigation of the Burgas attack” on Tuesday.

The Bulgarian foreign ministry has declined to comment on a report that an investigation will link Hizbullah to the July 2012 tourist bombing that killed five Israelis.

On Thursday, Israel's Channel 2 reported that the Bulgarian investigation, which will be released soon, found Hizbullah was behind the bombing in Burgas that killed the five tourists and their Bulgarian driver.
