The Sudanese Civil Aviation Authority announced in a statement today, Saturday, that it has extended the closure of airspace for all flight operations until May 31. The authority added, "This does not include humanitarian aid flights and evacuation flights after obtaining permission from the relevant authorities." The Sudanese airspace was closed to regular flight operations after the outbreak of military conflict between the country's army and the Rapid Support Forces in mid-April. In this context, a warning was issued that any violation of the airspace will be dealt with decisively.
