Coming only days after two other missiles were launched and a day after allegations were made the country is shipping munitions to Russian forces in Ukraine, North Korea continued actions its neighbours say are destabilising the region.South Korea's Joint Chiefs of Staff said the missiles flew 350 km (217.5 miles) and 250 km, respectively, after being fired at around 4:30 p.m. (0730 GMT) from the Sunan area of the North Korean capital Pyongyang."We will track and monitor developments together with the United States in preparation for additional provocations by North Korea, while maintaining a firm readiness posture based on our ability to overwhelmingly respond to any provocations by North Korea," the Joint Chiefs of Staff said in a statement.The White House said on Thursday that North Korea completed an initial arms delivery of infantry rockets and missiles to a private Russian military company, the Wagner Group, to shore up Russian forces in Ukraine.Canada on Friday levelled its own charges that North Korea had supplied the Wagner Group with weapons, saying the delivery "clearly violates international law and United Nations Security Council resolutions.""
