North Korea said on Tuesday it has decided to suspend disabling its nuclear facilities and will consider restoring the Yongbyon nuclear reactor because the United States had violated a six-party disarmament deal.
"We have decided to immediately suspend disabling our nuclear facilities," the North's KCNA news agency quoted a foreign ministry official as saying.
Regional powers have been pressing North Korea to accept a tough verification mechanism to check Pyongyang's declaration of its nuclear programme made in July. The United States has put off taking the North off its list of state sponsors of terrorism until there is agreement on verification.
