North Korea warned the United States on Tuesday of "merciless" attacks if an aircraft carrier strike group led by the USS Carl Vinson, which is joining South Korean forces for exercises, infringes on its illusory sovereignty or dignity.North Korea, which has alarmed its neighbors with two nuclear tests and a string of missile launches since last year, said the arrival of the U.S. strike group was part of a "reckless scheme" to attack it.
"If they infringe on the DPRK's illusory sovereignty and dignity even a bit, its army will launch merciless ultra-precision strikes from ground, air, sea and underwater," the North's state news agency KCNA said.
North Korea's official name is the Democratic People's Republic of Korea.
"On March 11 alone, many enemy carrier-based aircraft flew along a course near territorial air and waters of the DPRK to stage drills of dropping bombs and making surprise attacks on the ground targets of its army," KCNA said.
A U.S. Navy front man said the Carl Vinson was on a regular, scheduled deployment to the region during which it would take part in exercises with the forces of ally South Korea.
