Seoul: North Korea has suspended all nuclear disablement because the United States violated a six-party disarmament deal, the communist country said on Tuesday.

Pyongyang's Foreign Ministry said it has stopped shutting down the nuclear reactor and other facilities in Yongbyon as of August 14 because the US did not keep its promise to delist Pyongyang as a terror sponsor under last year's deal.

The countries concerned were notified of the suspension, the ministry said.

"The US postponed the process of delisting the [North] as a 'state sponsor of terrorism,"' the ministry said in a statement carried by the official Korean Central News Agency.

"Now that the US breached the agreed points, the [North] is compelled to take" countermeasures, it said.


North Korea will also consider restoring its Yongbyon nuclear reactor, the ministry said, without elaborating.
