The purpose of the flight stop is to move forward with even more and sharper efforts to isolate Russia, Hans Dahlgren explains.

- It is an attempt to influence Russia so that they really regret and take back the invasion of Ukraine.

It's about hours

It is important that the EU stays together on the issue, says Dahlgren.

Sweden will therefore push for a joint flight stop at an extra meeting with EU foreign ministers that will take place later on Sunday.

- If there is such a joint decision, then it will be possible to implement it very quickly.

It can be just hours or a day.

The ban would cover all Russian airlines.

This means major restrictions on air traffic, where holiday travel is also stopped.

- If we have a ban on Russian aircraft flying over Sweden, they must of course not land here either, Dahlgren says.

Sends fighter jets

In the event of a decision to stop Russian planes over Swedish airspace, the Swedish Civil Aviation Administration will be informed.

Should Russia then violate the airspace, there are definite instructions for how the Swedish Armed Forces should act, says Lieutenant Colonel Joakim Paasikivi.

- Then you send up a Swedish fighter aircraft that may reject the offending aircraft. It sometimes happens that commercial aircraft lose radio contact and then you can send up fighter aircraft.

Should it be state aircraft, ie military aircraft or government aircraft, the regulations are a little different but basically the same, he says.

Danish and Finnish ban

A large number of European countries have closed or are in the process of closing their respective airspace to Russian bypasses.

- We have decided that we will close our Danish airspace to Russian flights, including private flights, as soon as possible, says Danish Foreign Minister Jeppe Kofod, who adds that a ban will take effect sometime on Sunday, according to TT.

Norway and Finland have also decided to close their airspace.

Finnish Transport Minister Timo Harakka announced the decision via Twitter.

It is not clear there when it may come into force.

Belgium, Bulgaria, Poland and the Czech Republic have taken similar decisions.

The same applies to Estonia, Latvia, Lithuania, Romania, Slovenia and Germany.
