As-yet unidentified tremors were detected in North Korea early Saturday near the site of previous nuclear weapons tests. While China labeled the 3.4-magnitude quake a "suspected explosion" that could be Pyongyang's second nuclear test in a matter of weeks, an official from South Korea's meteorological agency said initial assessments indicate it was more likely a natural earthquake. North Korea has not commented either way.
On Friday, North Korea's foreign minister, Ri Yong Ho, said his government might test a hydrogen bomb over the Pacific Ocean. "This could probably mean the strongest hydrogen bomb test over the Pacific Ocean," Ri announced. "Regarding which measures to take, I don't really know since it is what Kim Jong Un does."
Also Friday, President Trump once again called North Korean leader Kim Jong Un "Rocket Man," the latest in a series of insults the two men have traded this week.
