The Russian Ministry of Foreign Affairs summoned Norway's caseload due to the seizure of Russian property against which a sharp protest was filed in connection with the arrest of Professor Molchanov's ship in the port of Branzburg based on claims of Ukrainian companies and five Russian real estate assets in Oslo. The Ministry of Foreign Affairs warned that the ship's winter mooring at the North Pole could lead to its collapse and damage to the environment. Moscow demanded compliance with international law and said it would ask for the arrests to be lifted.
