According to Air India, the Mumbai-Newark flight has made a "precautionary landing at London Stansted Airport due to a bomb threat". The flight was escorted by an RAF Typhoon, reports say. The Typhoon aircraft were authorised to fly at supersonic speeds to escort the Air India plane for operational reasons, the Defence Ministry reported.
An Air India official has stated that the bomb threat on tje Mumbai-New York flight was a hoax; the plane is back in the air after security check.
The flight had left Mumbai early in the morning and was bound for Newark Liberty International Airport in greater New York City.
London's Stansted Airport later stated on Twitter that its runway had reopened and was fully operational after the "precautionary landing".
