US Secretary of State Rex Tillerson said Wednesday President Donald Trump was simply using language "that Kim Jong-Un would understand" when he gave Pyongyang an apocalyptic warning of "fire and fury" over its weapons program.

"What the president is doing is sending a strong message to North Korea in language that Kim Jong-Un would understand, because he doesn't seem to understand diplomatic language," he said.

Tillerson was talking to journalists aboard his plane en route to the US territory of Guam, where North Korea had warned it was considering missile strikes.
