Donald Trump has lashed out at the Danish Prime Minister during a "horrendous" 45-minute phone call as the duo discussed Greenland's future. The heated discussion has been described as "explosive" and was driven by Trump's demand that securing Greenland was required for national security purposes.

Anders Vistisen, a Danish member of the European Parliament, has told U.S. President Donald Trump to "f*** off" after Trump again expressed interest in purchasing the island of Greenland. Newsweek has contacted the White House for comment via email.

During last week's tense call with the Danish premier, Trump insisted he was serious about taking over Greenland, the Financial Times reported, raising fears about the future of trans-Atlantic relations.
