Qatari authorities have failed to investigate the deaths of thousands of migrant workers over the past decade, despite evidence of links between premature deaths and unsafe working conditions, Amnesty International said today. The organization’s new report, In the Prime of their Lives, documents how Qatar routinely issues death certificates for migrant workers without conducting adequate investigations, instead attributing deaths to “natural causes” or vaguely defined cardiac failures. These certifications – described by one leading pathologist as “meaningless” – rule out the possibility of compensation for bereaved families, many of whom are already facing financial difficulties after losing their main breadwinner.
