The European Union must take collective action against Hezbollah, Bulgarian Foreign Minister Nikolai Mladenov said Monday morning.Mladenov attended a meeting in Brussels to brief his counterparts on an initial investigative Bulgarian report which blamed Hezbollah for the bombing outside the Burgas airport that killed five Israeli tourists and a Bulgarian bus driver last July.“We believe the attack that happened in Burgas last year was organized by people connected to the military wing of Hezbollah,” Mladenov said.“We in Europe need to take collective measures to make sure that such attacks will never happen again on EU soil, that we are protected as the EU,” he said.
