Washington, June 6 (ANI): None of the four air samples taken from the "cloud" from North Korea's purported May 25 nuclear test prove that North Korea tested a nuclear device, Fox News has quoted a senior U.S. defense official, as saying.
The official added that the negative results in the atmospheric samples do not rule out a nuclear test. The samples simply cannot prove for certain that a nuclear device was detonated, and therefore it is impossible at this time for the Pentagon to know with any accuracy what its potential yield was.
U.S. intelligence authorities are still operating under the assumption that a test took place last month, he said.
The United States has told South Korea it will impose its own financial sanctions on the North apart from punishments that the U.N. has been mulling for Pyongyang's latest violation of U.N. Security Council resolutions, a news report said Friday.
ast week, Pyongyang conducted a barrage of missile launches and an underground nuclear test that violated previous U.N. Security Council sanctions.
The North also appeared to be preparing for more missile tests, including one believed to be capable of reaching the U.S. (ANI)
