Newly-instated US Secretary of State John Kerry on Tuesday overnight urged the international community, and particularly European states, to take immediate action against Hezbollah.

"We need to send an unequivocal message to this terrorist group that it can no longer engage in despicable actions with impunity," he said following the release of the Bulgarian report that found Hezbollah was behind the July 2012 bus bombing in Burgas that killed five Israelis and a Bulgarian bus driver.

"We are prepared to do all within our power to assist the Government of Bulgaria in bringing those responsible for the Burgas attack to justice," Kerry added.
