SEOUL—North Korea opposes war but would use nuclear weapons if South Korea attacked, Kim Yo Jong, the powerful sister of leader Kim Jong Un, said on Tuesday, in a warning that analysts said is probably aimed at the South’s incoming conservative president.
Kim Yo Jong, a senior official in the North Korean regime, said it was a “very big mistake” for South Korea’s minister of defense to make recent remarks discussing attacks on the North, state news agency KCNA reported.
