The airline canceled 22 flights departing from Moscow's Sheremetyevo Airport and 31 incoming flights operated both independently and jointly with its subsidiary Rossiya Airlines, pro-government news agency Interfax said.

Russian prosecutor said it opened a criminal investigation into the cyberattack targeting Aeroflot, the largest airline in Russia.

Russian airline Aeroflot cancelled dozens more flights on Tuesday but said it had now stabilised its schedule after a major cyberattack a day earlier, and the transport ministry said the issue had been resolved.
