President Trump’s recent comments about North Korea were “a declaration of war,” the country’s foreign minister said Monday, according to Reuters.

“In light of the declaration of war by Trump, all options will be on the operating table of the Supreme leadership of DPRK,” Ri Yong Ho said in New York.

Trump ratcheted up his warnings to North Korea on Saturday, suggesting that it “won’t be around much longer” if it continues its provocative rhetoric.

“Just heard Foreign Minister of North Korea speak at U.N.,” Trump tweeted. “If he echoes thoughts of Little Rocket Man, they won’t be around much longer!”
