The Russian airline Aeroflot was forced to cancel dozens of flights on Monday after a shadowy pro-Ukraine hacking group claimed responsibility for what it said was a crippling cyber-attack.

The national carrier did not provide further details about the cause of the problem or how long it would take to resolve, but departure boards at Moscow's Sheremetyevo airport turned red as flights were cancelled at a time when many Russians take their holidays.
