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.

The Carl Vinson is the first U.S. carrier to visit Busan since the USS Theodore Roosevelt docked there on June 24. Days later, the Theodore Roosevelt and its strike group took part in Freedom Edge, the first major trilateral maritime and aerial exercise involving the United States, South Korea and Japan.

North Korean leader Kim Jong Un's influential sister said Tuesday that the deployment of a U.S. aircraft carrier to South Korea would prompt Pyongyang to bolster its nuclear arsenal and ramp up military provocations.
