Construction work on a stadium set to host games for the 2018 World Cup in the Russian city of Samara has come to an abrupt and unexpected stop, the Associated Press reports. Russia's Sports Minister, Vitaly Mutko, made the announcement on Sunday, adding that "the stadium has come to a halt; this issue must be resolved."

Apparently, Mutko did not cite a reason for the work stoppage. Mutko had said previously that work at the stadium was "two or three months" behind schedule.

The report pointed out that the regional government told state newspaper Rossiiskaya Gazeta that it was caused by a demand from the chief contracting company because of an increase in costs.

The expectation is for the stadium to still open in 2017, but if this delay continues, it may put that timeline in jeopardy if a resolution is not found.
