Moscow residents desperately rushed to nuclear bomb shelters on Tuesday after hackers broadcast imminent threat alerts across the city's warning systems.
Footage shows a terrified female passenger reacting to the warning on the intercom onboard a bus in the Russian capital.
'Attention, attention! Ukraine is threatening us with a nuclear bombardment', the warning system announces.
'Everyone to the shelters!'.
Moscow transport officials quickly clarified that the alarming messages came from unknown hackers, and assured commuters there was no need to panic.
