Finland stops Russia-linked vessel over damaged undersea power cable in Baltic Sea

Remove the restrictions Russia attacks other countries power grids with impunity why are there restrictions on attacking them handicapping your allies in war is stupidity

Russian ships should be considered as pirates then every nation has the right to confiscate their ships in international waters
