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.

Two pro-Ukraine hacking groups claimed to have carried out a year-long operation to penetrate Aeroflot's network

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.
