The international community on Wednesday condemned North Korea’s statement that it carried out successfully hydrogen bomb test.

The United Nations Security Council will hold an emergency meeting later due to the reported test.

Until now, it has not been confirmed that the bomb test has been conducted, while South Korean President Park Geun-hye called for an accurate analysis of the North’s claim.

“It’s not only grave provocation of our national security, but also an act that threatens our lives and future. It’s also a direct challenge to world peace and stability,” she said.

Moreover, Ned Price, the spokesman for the National Security Council, said: “While we cannot confirm these claims at this time, we condemn any violation of U.N. Security Council resolutions and again call on North Korea to abide by its international obligations and commitments.

“We have consistently made clear that we will not accept it as a nuclear state. We will continue to protect and defend our allies in the region, including the Republic of Korea, and will respond appropriately to any and all North Korean provocations.”

Federica Mogherini, the European Union’s foreign policy chief, said if confirmed, the test would be “a threat to the peace and security of the entire Northeast Asiaregion.”

International Atomic Energy Agency (IAEA) Director General Yukiya Amano added that if there was a nuclear test, it is “deeply regrettable,” while urging North Korea to fully implement all relevant U.N. Security Council and IAEA resolutions, as USA Today reports.

Japan also condemned the bomb test claims with Prime Minister Shinzo Abe arguing the test represents a threat to Japanese security and is totally intolerable, according to Kyodo News Service.

China, which is North Korea’s main ally, said it “firmly opposes” the test.

“China is steadfast in its position that the Korean Peninsula should be denuclearized and nuclear proliferation be prevented to maintain peace and stability in Northeast Asia,” Foreign Ministry spokesperson Hua Chunying said, according to official Xinhua agency.

“We strongly urge (North Korea) to honor its commitment to denuclearization, and to cease any action that may deteriorate the situation,” she added.

British Foreign Secretary Philip Hammond said he and his Chinese counterpart Yang Jiechi agreed to work with the members of the U.N. Security Council toward “a robust international response.”

Australian Foreign Minister Julie Bishop said the test “confirms North Korea’s status as a rogue state and a continuing threat to international peace and security.”

French President Francois Hollande condemned “this unacceptable violation of Security Council resolutions” and called for “a strong reaction from the international community.”
