Swedish authorities are flagging a wave of denial-of-service attacks during the past week. A pro-Russian hacker group claims responsibility on Telegram.

The group claims that the attacks are in response to the expulsions of Russian diplomats and the Swedish investigation into the attack on Nord Stream. The attacks are so-called DDOS attacks that are harmless to the authorities' activities, but which prevent visits to their websites. The Riksdag website was also targeted earlier this week and could not be reached.
