NATO is talking about improved Arctic security, says the alliance's secretary general. Some of those talks reportedly involve a European troop presence in Greenland. It's a remarkable turnaround for an alliance that has until recently tried to ignore the region.

Britain is discussing with NATO allies how to enhance Arctic security against Russia and China. Transport Secretary Heidi Alexander said Sunday that these talks are routine and not a response to U.S.

The European Union can help provide security for Greenland, should Denmark request it, the European Commissioner for Defence and Space said, warning that a U.S. military takeover of the island would be the end of NATO.

The Trump administration has repeatedly said the U.S. should be in control of Greenland, which is part of Denmark and NATO.

Trump’s threat to annex an autonomous part of Denmark has plunged NATO into an unprecedented situation: An alliance based on collective defense now faces the prospect that one member might attack another.

The comments followed media reports that the UK was in talks with its European allies about deploying a military force to Greenland.

Germany is planning to set up a joint Nato operation in the Arctic in an effort to dissuade Donald Trump from annexing Greenland.

The response comes amid concerns over Russia's continued military build-up in the region and its close ties to China.
