Meta, the parent company of Facebook, says it has evidence that the Belarusian secret service (KGB) used fake accounts to sow unrest over the migrant crisis at the Belarus-Poland border.

The findings are described in a company report (pdf).

The fake accounts posted critical messages about Poland in English, Polish and Kurdish, Meta reports.

"Included were photos and videos of Polish border guards allegedly violating migrants' rights."

In order to shape the fake accounts, some accounts were provided with profile pictures created by the computer, using deepfake technology.

Meta claims to have identified and deleted 41 Facebook accounts linked to the Belarusian KGB.

Four Instagram accounts and five Facebook groups were also deleted.

There has been unrest for weeks at the Belarus-Poland border, where Belarus is sending thousands of migrants into the EU.

By flooding the EU with migrants, Belarusian dictator Lukashenko would like to fight a feud with the EU.

The EU punished Belarus, among other things, because Lukashenko's regime uses violence against opponents of the Belarusian government and because freedom of the press is under pressure.

Also fake accounts that tried to keep migrants out of the EU

Meta also found a network from Poland with fake accounts posing as migrants from the Middle East.

Those accounts tried to persuade migrants not to enter the European Union.

It is unknown who is behind those messages.

"In the messages, the fake accounts claimed to share their own negative experiences with the crossing from Belarus to Poland," writes Meta.

"They shared messages about how difficult life was in Europe, about a strict anti-migrant policy in Poland and about neo-Nazi activities in Poland targeting migrants."
