The Swedish teenagers are suspected of the explosion at Israel's embassy in Copenhagen earlier in the week.
Generally, terrorist crimes are a very serious suspicion, it's a serious crime. When it comes to the specific case, it's a matter for the Danish police, says Karin Lutz, press spokesperson for Säpo.
It's the Danish police who are in charge of the investigation, but they have close cooperation with both Swedish police and Säpo.
Violence-approving extremism and terrorism and similar are borderless, it moves across borders. Therefore, it's incredibly important that we have close cooperation both nationally and internationally to prevent terrorist threats, says Karin Lutz.
We always have close cooperation with the police and share information to the extent it's possible generally. We have a dialogue, but it's the police's investigation.
Just hours before the incident in Copenhagen, a shooting occurred at Israel's embassy in Stockholm, and according to the Swedish prosecutor, there is a connection between the events. However, there are no terrorist suspicions for the Swedish case, confirms Säpo.
It's a matter for the Police Authority what crime it is, but currently, it's not being investigated as a terrorist crime, says Karin Lutz.
The arrested men, who are 16 and 19 years old, are suspected of having transported five hand grenades and of having thrown two of them against a rooftop terrace in Hellerup north of Copenhagen, where Israel's embassy is located.
