MOSCOW, October 23. /TASS/. The world's largest passenger jet A380 en route from Dubai to Moscow cannot land in Moscow's Domodedovo Airport due to safety restrictions, a source in the air industry told TASS.

"The airplane is now circling in the Penza Region, waiting for the resumption of Moscow airports' operations or the decision to fly to an alternate airfield," the source said. The airplane flight data are also confirmed by air traffic online monitoring services.

Moscow airports are closed for inbound and outbound flights, the Russian Federal Air Transport Service, Rosaviatsiya, said earlier.
