BRUSSELS (Reuters) -NATO Secretary-General Mark Rutte and Danish Prime Minister Mette Frederiksen agreed at a meeting on Tuesday that allies need to focus on strengthening defences in the Arctic, a source familiar with the talks told Reuters.

The prime minister does a European tour while announcing more spending on security around the island, following President Trump’s stated desire to have Greenland, a semiautonomous Danish territory, as part of the U.

One of the Russian ships was detained Sunday by the Swedes for further investigation, the Journal reports. The ship’s owner blamed bad weather and said his crew is innocent. The owner of one of the other ships—Norwegian-flagged cargo ship Silver Dania—agreed to have it towed into port for further inquiry.

The EU and Nato have taken a vow of silence over Greenland after Denmark requested its key allies refrain from reacting to Donald Trump’s threats to seize the Arctic island.

Europe is uniting in response to US President Donald Trump’s efforts to appropriate Greenland. Danish Prime Minister Mette Frederiksen sought to drum up support from German Chancellor Olaf Scholz in Berlin and French President Emmanuel Macron in Paris before a meeting with NATO Secretary General Mark Rutte.

Increased Russian military activity in the Baltic Sea has resulted in global calls for Denmark and other nations to inspect Moscow's oil tankers.

Frederiksen’s efforts have not been limited to diplomatic dashes. Denmark has announced a $2bn Arctic security plan, including new warships, drones and satellite capabilities to bolster its presence in Greenland, which is a self-governing territory within the Kingdom of Denmark.

An overwhelming majority of Greenlanders have rejected US President Donald Trump, saying they do not want to be bought by America, according to an opinion poll. The first survey of Greenlanders since Trump renewed his interest in buying the Arctic island found that 85 per cent did not want to leave the Kingdom of Denmark and become part of the US.
