South Koreans should turn against their president and give up cooperation with the U.S. on sanctions against North Korea, sister of the DPRK leader Kim Yo Jong suggested in a new statement released by state media Thursday.

Kim called South Korea a U.S. “stooge” and “no more than a stray dog gnawing at a bone given by the United States,” according to the state-run Voice of Korea, echoing comments she made two days earlier calling Washington a “scared barking dog” after convening a Security Council meeting to condemn DPRK weapons tests.
