North Korea has strongly criticized the United States over what it calls “political and military provocations.” The statement came after the US Navy aircraft carrier USS Carl Vinson docked in the South Korean port city of Busan on March 2.

A visit by a U.S. aircraft carrier to South Korea prompted a warning from the sister of North Korea’s leader that Washington and Seoul “should not test” the communist regime.

The U.S. aircraft carrier USS Carl Vinson arrived at the southern port city of Busan in South Korea on Sunday as a show of force against North Korea, South Korea's navy said.
