US President Donald Trump has been discussing "a range of options" to acquire Greenland, including use of the military, the White House said.
In a statement, the White House told the BBC that acquiring Greenland was a "national security priority".
It comes after Trump repeated over the weekend that the US "needed" Greenland – a semi-autonomous region of fellow Nato member Denmark – for security reasons.
European allies have been rallying in support of Denmark following the US remarks. Danish Prime Minister Mette Frederiksen warned on Monday any attack by the US would spell the end of Nato.
The White House said on Tuesday: "The president and his team are discussing a range of options to pursue this important foreign policy goal, and of course, utilizing the US military is always an option at the Commander-in-Chief's disposal."
