Sweden and Finland undertake to process ongoing and resolved extradition requests for persons whom Turkey classifies as terrorist suspects "quickly and carefully", in order for Turkey to give the green light to the countries' NATO applications.

According to a survey by Sweden's Radio Ekot, at least 13 of the people Turkey is requesting extradited from Sweden lack Swedish citizenship.

Greater risk of extradition

People without Swedish citizenship run a greater risk of being extradited, and asylum seekers run the greatest risk, explains Mark Klamberg, professor of international law at Stockholm University, to Ekot.

In order for a person who lacks Swedish citizenship to be extradited, it is required that they have committed an act that is classified as a crime in both countries.

Sweden also does not extradite people who have committed political crimes, but here the legislation differs for asylum seekers.

- In the Extradition Act, there is a ban on deportation for political crimes.

But there is no corresponding rule when it comes to asylum legislation, says Mark Klamberg to the radio.
