The Greek National Tourism Office (GNTO) and Greek Consulate office in Berlin was attacked in the early morning hours of Friday by a group of 10-15 vandals wearing masks, resulting in extensive material damage to the GNTO facility.

The vandals broke the glass entrance door to the GNTO office on the ground floor of the building and caused substantial damage to the facility.

They also threw black paint at the building and bottles, which reached the balcony of the third floor, where the Greek Consulate is housed.

According to the account of an eye-witness, who alerted the police, the vandals spoke fluent German.

The assailants left an unsigned proclamation at the scene with an anti-capitalist content, calling their attack an act of solidarity with those who have recently faced "state terrorism".

The German police are investigating the circumstances of the attack and are searching for the perpetrators.
