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.

SEOUL (Reuters) - North Korea's Kim Yo Jong, the powerful sister of leader Kim Jong Un, criticised the United States' "policy of confrontation" and said it justified the nuclear state increasing its arms, state media KCNA said on Tuesday.
