Haryana has blamed Delhi for rising Covid-19 cases in Gurgaon and Faridabad and has decided to tighten its borders with the Capital. Those travelling from Delhi to these satellite towns will need passes from the govt. Even health care workers, media employees and those providing essential services will need the passes, authorities said. The measures came as Haryana Health Minister Anil Vij said many who work in Delhi and stay in Haryana have become "corona-carriers". At least two other borders - Sonipat and Jhajjar - were sealed earlier amid the Covid-19 outbreak.
