North Korea conducted their third, and largest, nuclear test today, in a move that has provoked neighboring China and the rest of the world. Here's an English translation of the announcement North Korean's heard today:
"The scientific field for National Defense has succeeded in the third underground nuclear test at a site in the north part of our country on February 12th, 2013. It was confirmed that the nuclear test was carried out at a high level in a safe and perfect manner using a miniaturized and lighter nuclear device with greater explosive force than used previously. It did not pose any negative impact on the surrounding ecological environment."
