North Korean leader Kim Jong-un presides over an urgent operation meeting on the Korean People's Army Strategic Rocket Force's performance of duty for firepower strike at the Supreme Command in Pyongyang, early March 29, 2013, in this picture released by the North's official KCNA news agency on Friday. North Korea put its rocket units on standby on Friday to attack U.S. military bases in South Korea and the Pacific, after the United States flew two nuclear-capable stealth bombers over the Korean peninsula in a rare show of force. Kim Jong-un signed off on the order at a midnight meeting of top generals and "judged the time has come to settle accounts with the U.S. imperialists in view of the prevailing situation", the official KCNA news agency said. | Foto: Reuters
