Soviet bombing of Sweden -40 and -44

I need some info about the soviet bombing of Pajala on February the 21st 1940 and the bombing of Stockholm on Februari 1944. All help is welcomed.

 

Some details from Jukka Mäkelä " Helsinki on fire"

On 22.2.1944 the Leningrad area bombers started showing signs of activity.Altogether some 220 bombers were soon in the air. From the earlier flying passage of the "weather" planes Turku was seen as the target by the Red Air force. As the bombers came closer to Turku the bombers somehow started wandering around the large area of islands, some of those even going all the way to Stockholm.
At the same time something even more weird was happening. The "weather" planes took off again and this time there were three planes instead of the two. This was considered quite weird as the "weather" planes could not help anymore the bombers already in the target area. These planes headed even further west and seemed to have a special target to go to.
As Finns finally could not see any other target for the planes than Stockholm the Finnish radar men were wondering if they should warn Stockholm.
No messages were sent as it was thought the Swedes would not believe Finns.

A bit later on a message was received " Three planes had bombed Stockholm".

Later on the Russians denied that the planes were theirs.

The reason why the "weather " planes bombed Stockholm stays open but in the book it is supposed that the Russian planes probaly flew according to radio links and possibly homed on the Swedish link.As well it is mentioned that the Russians might have wanted to pressure the Swedes on telling Finns to surrender.
