A 40-year-old British man has died while working on the 2022 World Cup stadium in Qatar.
Organisers said the man, who is not named, died on Thursday working at Khalifa International Stadium.
A statement from Qatar said: 'The relevant authorities have been notified and the next of kin has been informed. An immediate investigation into the cause of this fatality is under way and further details will be released in due course.
The man was an employee of a 'specialised German contractor', according to the BBC.
In a report by Amnesty International in October, workers claimed they are subject to appalling living conditions, feel threatened by their superiors, have been lied to about their salary and feel trapped.
Fifa has denied these claims.
Metro.co.uk approached the Foreign Office for comment.
How many people have died during construction?
The number of deaths of worker building Qatar's stadiums was first brought to light in 2013.
A report by the International Trades Union Confederation, claimed there had been 1,239 deaths since construction begun in 2010.
The ITUC asked the embassies of Nepal and India, two countries which are the source of many of the migrant workers, to tally the number of deaths.
