During a phone talk, Mr. Abe said that the international community needs to take resolute action to prevent further provocations by Pyongyang. President Obama said Washington will take steps to ensure the security of its allies, including Japan.

Japanese Foreign Minister Fumio Kishida spoke with his counterparts from the EU and South Korea about Pyongyang’s H-bomb test.

Earlier, the UN Security Council held an emergency meeting to work out measures to deal with the situation.  United Nations Security Council members strongly condemned North Korea’s announcement of its latest nuclear test, calling it “profoundly destabilizing regional security.”

UN chief Ban Ki-moon demanded Pyongyang cease any further nuclear activities and meet its obligations for “for verifiable denuclearization.”

At the UN Security Council’s meeting, South Korean President Park Geun-hye strongly criticized North Korea’s “H-bomb” test and called on the international community to take more sanctions to make Pyongyang pay for its violation of the UN Security Council’s resolutions. South Korean Defense Ministry spokesperson Kim Min-seok said South Korean army would take necessary measures and cooperate with the US to deal with the situation.

On Wednesday, the US government said results of the initial analysis are not consistent with North Korean claims of a successful hydrogen bomb test. Experts said it may take several days to identify the nuclear facilities that Pyongyang has activated.
