Wednesday's test of the Pukguksong-3 missile, which North Korea describes as a type of missile capable of being launched from a submarine, is seen as the North's most high-profile weapons launch since it began diplomacy with the United States early last year.

John Bolton: "The firing of these missiles don't violate the pledge that Kim Jong Un made to the president about intercontinental-range ballistic missiles,"

North Korea said it is infuriated over U.S.-South Korean plans to hold military drills that the North says are invasion rehearsals and proof of the allies’ hostility to Pyongyang.

Trump tweeted that the news represented "big progress," and said he was looking forward to his upcoming summit with North Korean leader Kim Jong-Un.

North Korea has been using its embassy in Berlin to procure parts for its missile program, the head of Germany’s BfV domestic intelligence agency told a German broadcaster.

China says it has not allowed any oil sales to North Korea that break U.N. sanctions.

Republican U.S. Senator Lindsey Graham on Sunday urged the Pentagon to start moving U.S. military dependents, such as spouses and children, out of South Korea, saying conflict with North Korea is getting close.

The annual U.S.-South Korean drill, called Vigilant Ace, will run until Friday, with six F-22 Raptor stealth fighters to be deployed among the more than 230 aircraft taking part.

The United States warned the North Korean leadership that it would "utterly destroyed" if war were to break out, after Pyongyang test fired its most advanced intercontinental ballistic missile, putting the U.S. mainland within range.

The notion of Chinese power over North Korea is so tantalizing that President Donald Trump has spent a good part of his young presidency playing it up.
