A U.S. nuclear-powered submarine arrived in the South Korean port city of Busan on Sunday, the Yonhap news agency reported citing the South Korean navy. The arrival of the USS Missouri, also known as SSN-780, comes after South Korea and the U.S. held their second Nuclear Consultative Group meeting in Washington on Friday. "Any nuclear attack by North Korea against the United States or its allies is unacceptable and will result in the end of the Kim regime," a joint U.S.-South Korean statement from the meeting said.
