There is no issue of a Grexit, German ambassador to Greece Peter Schoof said on Tuesday while stressing the importance of supporting Greece on the refugee issue in order to protect the Schengen zone, speaking at an event organised by the "Center for Democracy and Reconciliation in Southeast Europe."

The “Group of People's Fighters” undertook responsibility for the attack on the German ambassadorial residence, on 30 December, through a proclamation sent to newspaper “Pontiki."

Domestic terrorism in Greece is not a new phenomenon. However, conditions in the country in a sixth year of recession are explosive and a recent re-emergence of politically motivated terrorism is adding more fuel to political and civic strife.
