Report: North Korea threatens to pull out of summit with U.S.

PYONGYANG, North Korea (KKTV) - With less than a month until its historic summit with the United States, North Korea is now threatening to back out.

This is according to a South Korean news agency, who cites the ongoing South Korea-U.S. military drills as a reason.

North Korea has loudly complained about the routine military exercises between the two nations for years, and at times has threatened action.

The two-week military exercise began last week.

South Korea's Yonhap News Agency reported that a high-level meeting between the Koreas Wednesday was canceled due to the exercises and that Pyongyang was questioning whether the summit with the U.S. should be canceled too.

The summit is scheduled for June 12 in Singapore.

This is a developing story and we will update as more information becomes available.
