A spokesperson told Reuters that objects scattered around the construction site for the Samara Arena, which is due to host six matches, including a quarter-finals, had caught fire.

This included construction debris, wooden planks and old plastic pipes.

It has been confirmed that no-one was injured.

An exact cause for the blaze has not yet been revealed by the Organising Committee or the Regional Government.

A similar incident occurred at the Vologograd Stadium in June, which was caused by a "violation of fire safety regulations during welding".

The stadium in Samara, the sixth largest city in Russia, will have a capacity of just under 45,000 and cost a reported $320 million (£243 million/€269 million) to build.

It will be the home of Russian Premier League side Krylya Sovetov after the tournament has concluded.

FIFA today confirmed that the main framework of the Samara Stadium was nearly complete, with 95 of the 96 blocks making up the venue's dome structure now in place.

World football's governing body said preparations have started for the renovation of the area surrounding the facility, including the demolition of the an old radio centre.

The spaces earmarked for new construction have also been levelled, according to FIFA in an update regarding progress at the various stadiums due to be used at the World Cup.

A total of seven arenas remain unfinished, with FIFA claiming they are all nearing completion.

The pitch is being laid at the Ekaterinburg Arena, while "the grass is already flourishing" at the Rostov Arena and the Nizhny Novgorod Stadium.

Preparations have finished at the Kaliningrad Stadium and specialists are expecting the seeds for the pitch to be planted next week.

A total of 12 venues will host matches at the tournament in Russia, which runs from June 14 to July 15.
