KCNA SEOUL (REUTERS) - North Korean leader Kim Jong Un orders the country's rocket units to be on standby to attack United States (US) military bases in South Korea and the Pacific in an emergency meeting on Friday after the US flew Stealth bombers in a show of force to Pyongyang.

The North's official KCNA news agency said Mr Kim signed off on the orders at a midnight meeting of top generals and "judged the time has come to settle accounts with the US imperialists in view of the prevailing situation".

"He finally signed the plan on technical preparations of strategic rockets of the KPA, ordering them to be standby for fire so that they may strike any time the US mainland, its military bases in the operational theaters in the Pacific, including Hawaii and Guam, and those in South Korea."
