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.

Ukrainian and Belarusian hackers who claimed responsibility for a major cyberattack on Aeroflot said Friday that they published the flight history of the Russian airline’s CEO despite official denials that any data had been leaked.
