Three young women have died in a stampede at a Hungarian nightclub.
Budapest police spokeswoman Katalin Fanni Horvath said thousands of people were caught up in the stampede and the victims may have been trampled by the rushing crowd.
Police have opened an investigation into the organisers and, along with medical investigators, are working to determine the cause of the deaths.
Police denied reports that the victims were stabbed.
The incident happened late on Saturday at the West Balkan nightclub in downtown Budapest, housed inside a communist-era shopping mall and office complex.
Witnesses told Hungarian media on Sunday that the three-floor disco was overcrowded.
