The West Bengal government on Saturday banned incoming flights to Kolkata from six coronavirus hotspots, including Delhi and Mumbai, from July 6 to 19. The decision came less than a week after West Bengal Chief Secretary Rajiva Sinha asked the Ministry of Civil Aviation to not allow flights into the state from high-prevalance areas.

“No flights shall operate to Kolkata from Delhi, Mumbai, Pune, Nagpur,Chennai and Ahmedabad from 6th to 19th July 2020 or till further order whichever is earlier,” Kolkata Airport said in a tweet. “The temporary restriction on arriving flights to Kolkata Airport is on the request of State Govt [government] to restrict movement from high prevalence cities of coronavirus cases.”

In his letter to the civil aviation ministry of June 30, Sinha had said that Bengal was witnessing a sharp increase in coronavirus numbers and a large number of cases were among people coming from other states. He had also asked the Centre to reduce the frequency of flights to Kolkata.
