In the past year, a handful of Swedish IS sympathizers have returned to Sweden.

Säpo is prepared for more people to arrive in the near future.

All Swedish children in the IS camps have reported anxiety, according to previous information.

But Swedish preparedness is lacking when it comes to dealing with IS sympathizers who return, says SVT's Sanna Klinghoffer, who has long covered the issue of Swedish IS affiliates.

Program for de-radicalization

She compares with Belgium and believes that the issue is being discussed between different authorities.

- In comparison with, for example, Belgium, where there is a de-radicalization program for returnees, Sweden is far behind, says Klinghoffer.

She continues:

- I do not know that there are de-radicalization programs in Sweden.

Then we should know that Sweden is third per capita in Europe when it comes to people who go to IS.

In total, around 150 people out of the 300 who traveled down to IS are estimated to have returned, according to previous information from Säpo.

A few have been convicted of crimes committed in the conflict zone, but how many have been investigated is unclear.

Few have been convicted

The number of Swedish children in the IS camps who have reported unrest is secret, but it concerns both children who have traveled from Sweden and children who have been born in the conflict zone.

The purpose of the reports of concern is, among other things, that the children's home municipalities should be able to prepare to receive them if necessary.

At the same time, the stricter routines around today's reception raise questions about how well it worked in the past when IS supporters returned from IS territory.
