1000 workers from Nepal, India and Bangladesh have already died constructing 2022 FIFA World Cup venue in Quatar

From The Guardian, which has done several exposes of abuse of foreign workers in homophobic Quatar:

     The report by the international law firm DLA Piper calls for changes to the much-criticised kafala system that ties workers to their employers. It also contains the Qatari government's own figure on the numbers of migrants who have died on its soil: 964 from Nepal, India and Bangladesh in 2012 and 2013. In all, 246 died from "sudden cardiac death" in 2012, the report said, 35 died in falls and 28 committed suicide.
     But the real purpose of the 135-page report, commissioned in the wake of Guardian revelations about appalling working conditions in Qatar, was to make recommendations for reform. The document was welcomed by human rights campaigners as a major step forward, particularly given early fears that DLA Piper's independence could be compromised by its work for Qatar-owned news network al-Jazeera.
