SEOUL, April 7 (UPI) -- Kim Yo Jong, the sister of North Korean leader Kim Jong Un, on Monday described South Korean President Lee Jae Myung as "frank and broad-minded" after he expressed regret over unauthorized drone incursions into the North, in a rare conciliatory remark from Pyongyang.

Lee addressed the issue earlier Monday during a Cabinet meeting, following last week's indictment of three individuals accused of carrying out incursions between September and January.

"Although this was not an act by our government, I express regret to the North Korean side over the unnecessary military tension caused by such reckless behavior," Lee said during the meeting.

In a statement carried by state-run Korean Central News Agency, Kim said Pyongyang "appreciated it as a very fortunate and wise behavior for its own sake."
