A new row over the future of Greenland has erupted between Denmark and the US after Donald Trump appointed a special envoy to the territory.
The US President announced that he had appointed Louisiana's governor Jeff Landry to the position on Sunday, saying "Jeff understands how essential Greenland is to our National Security".
Mr Landry then wrote on X: "It's an honor to serve you in this volunteer position to make Greenland a part of the US."
But Greenland is currently a semi-autonomous part of Denmark, which is unhappy about Trump's latest move. The country has summoned the US ambassador in protest, with its foreign minister saying the move shows the US is still interested in the vast Danish territory.
Trump has repeatedly called for the US to take over over the mineral rich and strategically located Arctic island, since winning his second term, and has not ruled out using military force to achieve it.
Denmark's foreign minister Lars Løkke Rasmussen said Landry's comments were "completely unacceptable" and that everyone - including the US - must show respect for Denmark's territorial integrity.
Greenland back in the headlines
In March, US Vice President JD Vance visited a remote American military base in Greenland and accused Denmark - a NATO ally of the US - of underinvesting there.
The issue then gradually drifted out of the headlines but, in August, Danish officials again summoned the US ambassador - following a report that at least three people with connections to Trump had carried out covert influence operations in Greenland.
On Sunday, Trump said: "Jeff [Louisiana's governor] understands how essential Greenland is to our national security and will strongly advance our country's interests for the safety, security, and survival of our allies, and indeed, the world."
Earlier this month, the Danish Defence Intelligence Service said in an annual report that the US was using its economic power to "assert its will" and threaten military force against friend and foe alike.

The report also highlighted the rising strategic importance of the Arctic to great power countries as "conflict between Russia and the West intensifies.
It went on to say that the growing security and strategic focus on the Arctic by the US would "further accelerate these developments".
Russian President Vladimir Putin has said Russia is worried about NATO's activities in the Arctic and will respond by strengthening its military capability in the polar region.
