SEOUL, South Korea -- North Korea vows to restart all mothballed nuclear facilities at main Yongbyon complex.
They were closed in 2007 as part of an international nuclear disarmament deal.
Tuesday's announcement follows weeks of warlike rhetoric from North Korea, including threats to launch nuclear strikes against the U.S.
Earlier, the White House said that despite bellicose rhetoric from North Korea the Obama administration has not seen changes in the regime's military posture.
White House press secretary Jay Carney said Mondays the U.S. has not detected any military mobilization or repositioning of forces from Pyongyang to back up the threats from North Korean leader Kim Jong Un.
Pyongyang has reacted angrily to U.S.-South Korean military drills and a new round of U.N. and U.S. sanctions that followed North Korea's Feb. 12 underground nuclear test.
Carney called the U.S. response "prudent." He noted that such tough talk from North Korea is part of a familiar pattern.
Carney says the White House takes the threats "very seriously." But he says the rhetoric "is consistent with past behavior."
