Police have reported arrests and vandalism after about 6,000 people gathered in Vienna to demonstrate against a ball that the protesters say serves as a venue for Europe's extreme right.
While most of the demonstrators were peaceful yesterday, police made about a dozen arrests. They also reported damage to shops and at least one police vehicle.
The protests are against a ball convened by Austria's right-wing Freedom Party that demonstration organisers say acts as a magnet for the far-right fringe.
Freedom Party officials deny that, and say they are the target of left-wing extremists.
Police are being criticised for declaring parts of the demonstration area off-limits for journalists.
Police officials say they only want to protect reporters from injury, but Austrian news organisations say the decision limits media freedoms.
