Over the past many weeks, the floating bodies of suspected Covid victims in the Ganga has foxed authorities and people living downstream in Uttar Pradesh and Bihar. There have also been reports of mass graves along the river, with disturbing panoramic shots of orange-coloured specks -- graves -- stark against the river's white sandbanks. A video has now emerged from Uttar Pradesh's Prayagraj where people are seen pulling off yellow shrouds covering unidentified graves, apparently so that it is harder to spot them. A similar exercise was carried out in Unnao, too.
