Russia and Ukraine say emergency alert apps were hit by apparent cyber-attacks

• Russia and Ukraine say their emergency warning systems have been hit by cyber-attacks

• The Emergency Ministry in Moscow says a "massive cyber-attack" on its alerts app could enable attackers to send false information - but insists its wider public alert system is "operating as normal"

• This comes shortly after Ukraine's air raid warning app sent out false warnings , following an apparent hack

• Ukraine has blamed Russia for the hack on its app, while Moscow is yet to say who is behind the cyber-attack on its app

• The alerts in Ukraine were sent out just minutes before the end of a localised ceasefire in the front-line Kherson region, our Ukraine reporter Abdujalil Abdurasulov writes
