A Russian propaganda campaign involving thousands of fake accounts on TikTok spreading disinformation about the war in Ukraine has been uncovered by the BBC.
Its videos routinely attract millions of views and have the apparent aim of undermining Western support.
Users in several European countries have been subjected to false claims that senior Ukrainian officials and their relatives bought luxury cars or villas abroad after Russia’s invasion in February 2022.
The fake TikTok videos played a part in the dismissal last September of Ukrainian Defence Minister Oleksiy Reznikov, according to his daughter Anastasiya Shteinhauz.
The BBC has uncovered nearly 800 fake accounts since July. TikTok says it was already investigating the issue and says it has taken down more than 12,000 fake accounts originating in Russia.
