Dutch police say they have dispersed a "huge" fight involving some "300 people" at a polling station in Amsterdam. The fight broke out on Sunday evening at the RAI conference centre in Amsterdam, where Turkish-Dutch voters could vote early ahead of Turkey's May 14 presidential election.

The parties to the conflict have not been designated by the authorities. Turkish President Recep Tayyip Erdogan, 69, faces the most uncertain election since coming to power, facing for the first time in two decades a united opposition.
