North Korea has announced it will restart nuclear facilities at its main complex, including a reactor shuttered in 2007 as part of talks on nuclear disarmament. A North Korean spokesperson said the move is aimed at boosting electricity production and “bolstering up the nuclear armed force both in quality and quantity.” Tuesday’s move is the latest in a series of escalating tensions between North Korea and the United States, which has been carrying out military drills with South Korea. On Monday, White House Press Secretary Jay Carney said there were no signs North Korea was actually preparing for an attack.

Jay Carney: “I would note that despite the harsh rhetoric we’re hearing from Pyongyang, we are not seeing changes to the North Korean military posture, such as large-scale mobilizations and positioning of forces. Now, we take this seriously — I’ve said that in the past — and we are vigilant, and we are monitoring the Korean situation very diligently.”
