North Korea has denounced what it said about the United States' decision to bring a nuclear-powered ballistic missile submarine into waters near the Korean peninsula.
Pyongyang warned that this step leads to a situation that "brings a nuclear conflict closer to reality."
The USS Michigan, a nuclear-powered submarine, arrived in the South Korean port city of Busan on Friday, underscoring Washington's commitment to responding to Pyongyang's growing threats, the military said in Seoul.
The US Navy's nuclear submarine, which is capable of launching "Ohio"-class cruise missiles, will dock in the southeastern port of Busan, South Korea, for the first time in six years, according to a declaration signed in April between Washington and Seoul, according to what the South Korean military said in a statement.
