North Korea vows to strengthen nuclear forces

North Korea’s foreign minister condemned the United States on Friday for flying supersonic bombers over South Korea earlier this week and vowed his country will strengthen its nuclear capabilities in defiance of multiple UN Security Council resolutions. In a defiant speech before the UN General Assembly, Ri Yong Ho said the Korean Peninsula ``has now been turned into the world’s most dangerous hot spot which can even ignite the outbreak of a nuclear war.’’ He blamed the United States and ``its hostile policy’’ against North Korea.
