Regular alerts warn Ukrainians to take shelter from incoming attacks but the system was compromised on Sunday
Ukraine and Russia have both said air alert apps were hacked on Sunday night after fake messages warning of attacks, including nuclear, were sent to users.
Ukraine's widely used app sent red-level air raid warnings across the country, with additional warnings of radiation, chemical attacks, and street fighting sent to some residents in areas including Kyiv.
A purported screenshot of a fake alert was shared on Telegram by Atesh, a partisan Ukrainian group operating inside Russian-held territory.
