North Korea delivered on its threat today, conducting a second nuclear test that angered governments around the globe. The country also apparently test-fired a short-range missile today, the White House said. Japan called for an emergency meeting of the U.N. Security Council. Russia's ambassador to the U.N. said a meeting is expected today.
North Korea announced its underground nuclear test a little more than an hour after the U.S. Geological Survey reported a magnitude 4.7 seismic disturbance at the site of North Korea's first nuclear test.
There was no immediate information on the yield of the weapon used in Monday's test. The Russian Defense Ministry said the explosion was between 10 to 20 kilotons. The U.S. State Department said it was analyzing the data.
