Condemnation for bomb at Hellenic Train offices

The Infrastructure & Transport Ministry condemned the bomb attack at the Hellenic Train offices on Syngrou Avenue late on Friday night.

"It is a criminal act that jeopardized the lives of people, staff and passers-by, at a central point in Athens and at a time of high traffic circulation. Nothing justifies terrorism, no act of violence metes out justice," Minister Christos Dimas said in a statement.

The act was also condemned by Alternat Minister Konstantinos Kyranakis. 

In a statement, Hellenic Train said that the bomb caused limited material damage without injuring staff or passers-by. "Our company unequivocally condemns every form of violence and tension that encourage a toxic climate which undermines every progress. This type of expression has no place in society," it said.
