N. Korea Claims Successful Nuclear Test

From Yonhap:

North Korea claimed that it successfully conducted its third underground nuclear test at its northeastern site on Tuesday, drawing strong condemnation from the international community, including the governments of South Korea and the United States.

Hours after an unusual seismic tremor was detected at the North's Punggye-ri nuclear test complex, Pyongyang's Korean Central News Agency (KCNA) said that the detonation was of a "high level" using a smaller device compared to its previous two nuclear tests, and that the test was carried out in a safe manner that did not affect the surrounding environment.

"The test was conducted in a safe and perfect way on a high level with the use of a smaller and light A-bomb unlike the previous ones, yet with great explosive power," the KCNA said in the English dispatch, adding that the test did not have any adverse effects on the surrounding environment.

"The specific features of the function and explosive power of the A-bomb and all other measurements fully tallied with the values of the design, physically demonstrating the good performance of the DPRK's (North Korea) nuclear deterrence that has become diversified."
