Meanwhile a mosque was attacked with Molotov cocktails in Uppsala, third attack of this type this week. Combined with the different car bombs in Malmo (see Nordic general thread), seems like right-wing terrorism is becoming a serious threat in Sweden.
The car bombs is believed (to my best knowledge) not to be connected with the extreme right, but something commited by criminals of non-Swedish origin. While the first "attack" on a mosque, lack evidence of being an attack and the "witness", who saw a person run away have not been found. It's believed to have been a fire accident in the mosque, and yes without a witness or any kind of evidence of it being a attack, I don't believe it to have been a attack.
The second two have been clear attacks.
So in short you should change your post to; "meanwhile two mosques have been attacked, likely by the Swedish far right".
