North Korea stages tactical nuclear attack drill

SEOUL, Sept 3 (Reuters) - North Korea conducted a simulated tactical nuclear attack drill that included two long-range cruise missiles in an exercise to "warn enemies" the country would be prepared in case of nuclear war, the KCNA state news agency said on Sunday. Pyongyang also said it would bolster its military deterrence against the United States and South Korea. KCNA also reportd that North Korean leader Kim Jong Un visited Pukjung Machine Complex, which produces marine engines, and a munitions factory to stress the importance of strengthening Pyongyang's naval forces. North Korea has been stepping up its military deterrence against Washington and Seoul and has criticized last month's summit agreement between the two on improving military cooperations.
