Qatar's construction industry is rife with abuse of migrant workers who are "treated like cattle", Amnesty International has claimed as it called on Fifa to help with the situation ahead of the 2022 World Cup.
The report, based on interviews with workers, employers and government officials, includes accounts detailing the non-payment of wages, dangerous working conditions and "shocking" standards of accommodation.
Dozens of construction workers were prevented from leaving the country for many months by their employers, with many workers subjected to forced labour, according to the organisation.
Researchers also claimed they heard a manager of one construction firm referring to workers as “the animals”.
The Secretary General of the organisation, Salil Shetty, called on Fifa to work with Qatari authorities and World Cup organisers to prevent abuses as construction for the 2022 tournament begins.
Qatar has unveiled its designs for a new football stadium to be built for the World Cup in 2022, featuring a cooled pitch and inspired by a traditional fishing boat.
The stadium will be built in the Al-Wakrah region, 10 miles from the capital Doha, and will cool the pitch to 26 degrees centigrade, while spectator stands will be cooled to between 24 and 28 centigrade.
Football's governing body FIFA has launched a consultation to decide whether the tournament should be held in November-December, rather than June-July when Qatar will be at its hottest.
The Qatar World Cup will not be moved to January or February 2022 because of the Winter Olympics, according to Fifa.
Fifa President Joseph Blatter said he also recognised the work that Qatar is already undertaking in relation to workers' rights.
Mr Blatter added: "The organising committee here and the state of Qatar are willing and they are able to organise the World Cup in June and July if required, with a system of air conditioning in the stadium.
"It would be totally disrespectful to the Olympic family and organisation when they have the Winter Olympic Games in January and February."
Future World Cup hosts Qatar have decided to remove a statue of Zinedine Zidane's infamous headbutt on Italy's Marco Materazzi in the 2006 World Cup.
Officials have not commented on the reason for its removal, but the artwork, which was unveiled earlier this month, had stirred complaints from religious conservatives who argued it was wrong to honour Zidane's unsportsmanlike act.
Cranes were brought in this week and on Thursday the statue's site along Doha's waterfront was empty.
The mother and boyfriend of a British primary school teacher feared dead after going missing in Qatar have paid emotional eulogies to her on Facebook.
Lauren Patterson disappeared in Doha in the early hours of Saturday. Local media claim she was last seen outside the city's five-star La Cigale hotel.
Her mother Allison Patterson, who is reported to have flown to Doha, wrote: "Thank you so much to everyone for all their wonderful words about Lauren. She was a truly remarkable girl my rock always there for everyone. I know she's in heaven now in her Daddy's arms."
The 24-year-old's boyfriend, James Grima, from Malta, wrote: "You really were the most smart, kind, beautiful and amazing woman I've ever met."
The family and friends of a 24-year-old British teacher missing in Doha have expressed fears for her safety.
Lauren Patterson, who teaches at a local primary school, went missing shortly after returning to Qatar on Friday from the UK, where she had attended her grandmother's funeral, according to her friends.
The Foreign Office said they were aware of British national reported misssng in Qatar, and that they were providing the family with consular assistance.
FIFA member Michel D'Hooghe has claimed it will be 2015 at the earliest before a final decision is made on the dates of the Qatar 2022 World Cup.
Asked when a FIFA taskforce might make a decision about moving the tournament to the winter, the Belgian said: "At the earliest in 2015. We need some concrete information - this will not be done in two days."
However, FIFA president Sepp Blatter said: ""It cannot be later than 2015 - probably the end of 2014."
