North Korea is threatening to cancel the forthcoming summit with the US due to ongoing military exercises between America and South Korea, according to reports.
A meeting between the two Koreas at a border village to discuss setting up military and Red Cross talks to reduce border tension and restart reunions between families separated by the Korean War has also been cancelled by Pyongyang, Yonhap News Agency said.
North Korea's Korean Central News Agency reported that Pyongyang was also questioning whether next month's summit between North Korea's Kim Jong-Un and US president Donald Trump can also take place as planned.
Yonhap said the two-week military exercise between the US and South Korea started on Friday.
"This exercise, targeting us, which is being carried out across South Korea, is a flagrant challenge to the Panmunjom Declaration and an intentional military provocation running counter to the positive political development on the Korean Peninsula," Yonhap quoted KCNA as saying.
"The United States will also have to undertake careful deliberations about the fate of the planned North Korea-US summit in light of this provocative military ruckus jointly conducted with the South Korean authorities."
The US State Department says it is operating on the assumption the summit will proceed as planned.
