The announcement comes the day before SVT, DR, NRK and Yle release the next episode of the series "The Shadow War" about Russian intelligence activities in the Nordic countries – which among other things focuses on Russian intelligence officers in Sweden.

"Sweden has today summoned Russia's ambassador Viktor Tatarintsev and informed him that five people employed at the embassy are asked to leave the country because their activities are incompatible with the Vienna Convention on Diplomatic Relations," Foreign Minister Tobias Billström (M) told SVT News.

Ambassador: "No comments"

Russian Ambassador Viktor Tatarintsev declined to comment on the matter.

"No comments," he told SVT.

Two weeks ago, Norway announced that it was expelling 15 Russian diplomats.

The last time Sweden expelled suspected Russian intelligence officers was in April last year, when three diplomats were expelled. This comes as several other European countries expelled Russian diplomats in response to the war in Ukraine.

SAPO: Every third is a spy

Recently, SAPO received a list of names of a number of suspected Russian intelligence officers that Uppdrag granskning identified.

The Swedish Security Service has previously stated that every third Russian diplomat actually works for one of Russia's intelligence services and that they pose a threat.

"These are state-employed individuals who have these assignments to simply gather information and influence a country in a direction that they want," says Daniel Stenling, head of the Swedish Security Service's counterintelligence, in an interview for the series "The Shadow War".

In recent weeks, SVT has made a number of revelations about Russian intelligence activities in Sweden and the Nordic region. Among other things, about suspected Russian spy ships that have been in Swedish waters.
