Greek police arrested more than a dozen people on Sunday evening as they demonstrated against the Prespa Agreement. The arrests were made outside the Athens Concert Hall where Prime Minister Alexis Tsipras was due to give a speech on the subject.
Protothema.gr reports that the demonstrators were attempting to hoist a banner outside the venue calling for a referendum on the Prespa deal.
Police moved in and arrested the group, whose members were transported to the main police headquarters in downtown Athens.
