Bulgaria has made official what most observers have known. The Balkan nation has named Hizb’Allah as the perpetrator of the terror attack in Burgas.

SOFIA (Reuters) – Two individuals with links to Lebanon’s militant group Hezbollah were involved in a bomb attack on a bus in the Bulgarian resort of Burgas that killed five Israeli tourists last July, Bulgaria’s interior minister said on Tuesday.

The conclusions of the Bulgarian investigation may open the way for the European Union to join the United States in branding the Iranian-backed Hezbollah a terrorist organization since there is now a clear connection to an attack on EU territory.

Three people were involved in the attack, two of whom had genuine passports from Australia and Canada, Tsvetan Tsvetanov told reporters after Bulgaria’s national security council discussed the investigation.

“We have established that the two were members of the militant wing of Hezbollah,” Tsvetanov said. “There is data showing the financing and connection between Hezbollah and the two suspects.”

This announcement comes days after Israel’s strike on a  Hizb’Allah convoy in Syria and various explosions in South Lebanon. This could add fuel to the fire.
