Firefighters have extinguished a blaze at a World Cup stadium in the Russian city of Volgograd.
Emergency workers were called to the stadium, which is still under construction, before 7 a.m. on Wednesday morning.
The fire began after a portable heater set light to a pile of styrofoam, according to the Volgograd region's Emergency Situation Ministry. Flames spread across an area of approximately 100 square meters before being extinguished, officials said in a statement.
No casualties were reported.
The Volgograd Arena is scheduled for completion later this year. It has a planned capacity of almost 45,000 people and will hold matches in the group stages of the FIFA 2018 World Cup.
