The Ministry of Civil Aviation said on Sunday no letter has been issued declaring a no-fly zone in and around the national capital.
The ministry in a tweet said it has come to its notice that a fake letter by the DGCA declaring a no-fly zone in and around Delhi is circulating on WhatsApp.
"It is clarified that no such letter/ order is issued by any civil aviation authorities," the ministry said.
The DGCA is the civil aviation regulator.
Specific details about the fake letter could not be immediately confirmed.
