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.

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 USS Carl Vinson, a Nimitz-class US aircraft carrier, docked at a key naval base in Busan, a southeastern city, on Sunday as part of Washington's efforts to strengthen extended deterrence against North Korean threats, according to the Seoul-based Yonhap News Agency.
