The violence erupted in the main fan zone, the square adjacent to City Hall. No major injuries were reported, but first-aid personnel had to treat some fans for *lo**y noses and other superficial injuries.

Turkey advanced to the semifinals against Germany by winning the penalty shootout after the match ended at 1-1 after 120 minutes.

Police said the fighting broke out in the few minutes between Croatia's goal in the second last minute of extra time and the Turkish equalizer just a minute later.

The Croatian fans were pulled to a fenced-off area by security personnel and treated on the spot, the Austria Press Agency reported.

Other skirmishes in front of the nearby Burgtheater - the city's major theater - ended with pushing and shoving and no injuries, police spokesman Walter Hladik said.

In the Ottakring district, police cordoned off several streets after a hail of bottles were thrown at officers in riot gear gathered to separate hundreds of Croat and Turkish fans. Ottakring has a large Turkish population.

Police said arrests were made, but couldn't immediately provide any numbers.
