SEOUL—North Korea did not answer routine calls on inter-Korean hotlines on Tuesday, South Korea said, hours after a senior official in Pyongyang warned the South and the United States over annual joint military drills set to begin this week.
Kim Yo Jong, the powerful sister of North Korean leader Kim Jong Un, accused South Korea of “perfidious behavior” for going ahead with the drills after North Korea agreed to restore hotlines in late July, having cut them last year amid rising tensions.
