The United States and Japan have called on the U.N. Security Council to hold an emergency meeting to discuss North Korea’s claim of a successful hydrogen-bomb test, an act that violates several international resolutions.“The DPRK’s nuclear test, if confirmed, is in clear violation of U.N. Security Council resolutions and is deeply regrettable,” the International Atomic Energy Agency said, the Guardian reported. “I strongly urge the DPRK to implement fully all relevant resolutions of the U.N. Security Council and the IAEA.”

U.S. State Department spokesman John Kirby said the test could not be independently confirmed. But North Korea has called its detonation “a perfect success” and the U.S. Geological Survey recorded a sizable earthquake near the site of supposed testing.

Still, the Associated Press found the level of explosion measured near the site was much smaller than what would have been recorded for an actual bomb. And so did Bruce Bennett, an analyst with the Rand Corporation, in the Guardian: ” The bang they should have gotten would have been ten times greater than what they’re claiming. So Kim Jong-un is either lying, saying they did a hydrogen test when they didn’t, they just used a little bit more efficient fission weapon, or the hydrogen part of the test really didn’t work very well.” FULL REPORT
