A North Korean musical show celebrating the anniversary of its late founder has conveyed an explosive message for the United States — one depicting a massive nuclear strike on an unnamed city.

State television footage aired of the chorus performance on Sunday, a day after Pyongyang used a huge military parade to mark the anniversary of the birth of founder Kim Il Sung, the grandfather of the current leader, Kim Jong Un.

Songs included "Peace Is Guaranteed by Our Arms" and "Revolutionary Armed Forces Uphold Leadership of Marshal Only," which the state-run Korean Central News Agency said represented "the rosy future of Kim Il Sung's Korea which will prosper for all ages" and demonstrated the country's power with its "independent nuclear weapons under the invincible leadership of Kim Jong Un."
