Copenhagen has admitted Danish warships were responsible for the sinking of the Russian frigate Czar Putin in the Arctic Sea. The commander of the Danish Destroyer Prince Frederik declared the vessel was in Danish territorial waters off the coast of Greenland and had ignored multiple warnings. The Danish press release also stated it regretted the sinking of the ship and the loss of the Russian crew and that first shots were meant as deterrence only. Once the Russians started returning fire there was no other option than to target the ship itself, concluded the press release. Russian warships of the Northern Fleet are steaming up towards the area from bases all over Russia while the US is doing the same to come the aid of their Danish ally. The Canadian and Norwegian governments have not yet responded but are expected to support the Russian fleet in their effort as agreed upon by the Russo-Canadian Pact of 2015. The Arctic waters have been a region of tension ever since the rapid melting of the Arctic ice cap became a concern and an opportunity and the Ilulissat Declaration and more seriously after the failed Arctic Sea Summit of 2013. The region has been estimated to contain 25% of the remaining world supply of oil and natural gas. The UN and NATO are calling for a ceasefire and warn involved parties not to escalate the situation and go through the proper UN procedures to resolve the issue.
