North Korea has conducted its second nuclear test, the country's state news agency KCNA announced today. The nuclear test was expected. Earlier this year North Korea conducted a failed intercontinental missile test.
“The current nuclear test was safely conducted on a new higher level in terms of its explosive power and technology of its control and the results of the test helped satisfactorily settle the scientific and technological problems arising in further increasing the power of nuclear weapons and steadily developing nuclear technology," KCNA announced.
The U.S. State Department condemned North Korea's announcement of its second nulear nuclear test as being in "blatant defiance" of the U.N. Security Council. South Korean President Lee Myung-Bak's office said the country was investigating the reported test and would hold an emergency meeting of its national security council. In Japan, Prime Minister Taro Aso's office said it has set up a special task force to look into the test and how to respond.
