Instagram users in Russia have been notified that the service will cease as of midnight on Sunday after its owner Meta Platforms said last week it would allow social media users in Ukraine to post messages such as “Death to the Russian invaders”.

The company said it would be wrong to prevent Ukrainians from “expressing their resistance and fury at the invading military forces”.

The decision was greeted with outrage in Russia, where authorities have opened a criminal investigation agains
