Saudi Arabia has agreed to investigate following a Sunday Telegraph investigation which revealed the Gulf State is keeping hundreds if not thousands of African migrants locked in cramped and unhygienic detention centres as part of a drive to stop the spread of coronavirus.  Conditions in the centres are so bad that people are dying and the images smuggled out have been compared to those of slave camps....“Emerging evidence of the shocking conditions in which African migrants are being held in Saudi detention centres is deeply disturbing and demands immediate action,” said [UK] Shadow Foreign Affairs Minister, Stephen Doughty...The story has sparked outrage across Africa and the Middle East, and has featured prominently on Al Jazeera and other Arabic media channels. A spokesman for the Secretary-General of the United Nations, António Guterres told The Telegraph, said the UN was also investigating.
