NATO ambassadors said Tuesday that they "condemn in the strongest terms" the latest nuclear weapons test by North Korea, calling it a "flagrant violation" of UN Security Council resolutions, dpa reported.
"This irresponsible act, along with the December missile launch, poses a grave threat to international and regional peace, security and stability," ambassadors to the military alliance wrote in a statement.
"We call on the North Korean authorities to cease immediately such provocative actions, to meet their obligations under international law and to comply fully with the decisions of the international community, as expressed by the United Nations Security Council," they added.
