MOSCOW, Nov. 24 -- Russian Sports Minister Vitaly Mutko Monday said the city of Kaliningrad could lose the right to host 2018 World Cup matches unless it resolves a dispute over the site of its stadium.

Kaliningrad was announced as one of 11 host cities in 2012 but has suffered repeated delays and is now under threat, warned Mutko.

It is not clear where the 35,000-seat stadium in Kaliningrad will be built.
