President Donald Trump has written a letter to Norway saying he no longer feels obligated to think purely of peace.
Mr Trump's letter — addressed to Norwegian Prime Minister Jonas Gahr Støre — followed after the Norwegian Nobel Committee did not award him the Nobel Peace Prize.
The president repeated his demand for control of Greenland in a letter first reported by PBS journalist Nick Schifrin.
Mr Gahr Støre said Mr Trump's message came in response to a short text message from the president of Finland Alexander Stubb and himself earlier in the day.
"I have repeatedly clearly explained to Trump that it is an independent committee that awards the Nobel Peace Prize," he said.

British Prime Minister Keir Starmer said on Monday that he did not think Mr Trump was considering military action in Greenland.
"On Greenland, the right way to approach an issue of this seriousness is through calm discussion between allies," Sir Keir said at a press conference on the threat from potential US tariffs over the Arctic island.
France's Finance Minister Roland Lescure said he would convene a meeting of his counterparts from the Group of Seven (G7) countries to discuss trade and sovereignty "in the coming days".
"We are fully supportive of Greenland and Denmark," Mr Lescure said.
"Blackmail between friends is obviously unacceptable."
