Why does Trump want Greenland and what could it mean for Nato?
US President Donald Trump insists his country needs to acquire Greenland for national security reasons and has not ruled out using military force.
While a possible purchase has also been suggested, Trump says he plans to take control of the island "the easy way" or "the hard way".
His demands have been rejected by Greenland's leaders and by Nato member Denmark, of which the island is a semi-autonomous territory.
Where is Greenland and why does it matter to Trump?
Greenland - the world's largest island which is not a continent - is located in the Arctic. At around 2.2m sq km (836,330 square miles) it is roughly six times the size of Germany.
It is also the most sparsely populated global territory, with a population of about 56,000 people, mostly indigenous Inuit people.
Its location between North America and the Arctic makes it well placed for early warning systems in the event of missile attacks, and for monitoring vessels in the region.Read more
