UNITED NATIONS (AP) — The United States and allies South Korea and Japan clashed with China and Russia Friday over North Korea’s latest satellite and ballistic missile launches and threats to use nuclear weapons that have escalated tensions in northeast Asia. In response, the U.S. and its allies have carried out an increasing number of military exercises. “There is a need for practical measures to reduce tensions, reverse the dangerous dynamic, and create space to explore diplomatic avenues.”North Korea’s U.N. Ambassador Joonkook Hwang said it should be his country – not the DPRK – that should claim the right to self-defense. He warned that a planned large-scale joint military exercise on the peninsula in August “practicing a scenario involving a nuclear war” will only increase tensions.
