North Korea says it'll cut off communication channels with South Korea

It said the decision was made by Kim Yo Jong, the powerful sister of leader Kim Jong Un, and Kim Yong Chol, a former hard-line military intelligence chief who Seoul believes was behind two 2010 attacks that killed 50 South Koreans. ``The South Korean authorities connived at the hostile acts against (North Korea) by the riff-raff, while trying to dodge heavy responsibility with nasty excuses,'' KCNA said. ``They should be forced to pay dearly for this.''
