ABUJA, May 18 — Nigeria impounded a plane operated by a British company for allegedly contravening a flight ban imposed to prevent the spread of the coronavirus, the aviation minister said yesterday.

Passenger flights into the country, with the exception of ones to evacuate people or repatriate Nigerian citizens, have been banned for weeks. The ban will remain in place until at least June 4.

Flights for essential services, such as the delivery of food supplies and items for humanitarian use, are permitted.

Aviation Minister Hadi Sirika said on Twitter yesterday that a plane had been impounded after the rules were broken.

Sirika said a UK company "was given approval for humanitarian operations but regrettably we caught them conducting commercial flights.”

The message added: "The craft is impounded, crew being interrogated. There shall be maximum penalty.”

James Oduadu, an aviation ministry spokesman, told Reuters later in a telephone interview that the plane was operated by a company called FlairJet.

FlairJet, a British private charter company that is an affiliate of Flexjet, in a statement said the matter was an "evolving situation.”

"We are continuing to respectfully work with the Nigerian authorities to resolve this situation,” it said. — Reuters
