Workers in Qatar renovating a stadium for the 2022 World Cup have suffered rights abuses two years after the tournament's organisers drafted worker welfare standards in the wake of criticism, Amnesty International said. According to a report released on Thursday, dozens of construction workers from Nepal and India were housed in squalid accommodation and barred from leaving the country by employers in Qatar who confiscated their passports. aljazeeraThe state of human rights in Qatar is a concern for several non-governmental organizations. Sharia law is the main source of Qatari legislation according to Qatar's Constitution. Flogging and stoning are legal in Qatar due to Sharia law. According to Human Rights Watch in June 2012 hundreds of thousands of mostly South Asian migrant workers in construction in Qatar risk serious exploitation and abuse, sometimes amounting to forced labor.
