PYONGYANG (NEWSCHANNEL 3) - One day after promising to restart its nuclear program, North Korea has taken another step to escalate tensions with South Korea and the U.S.
The country's latest move comes a day after the country threatened to restart a nuclear reactor and a uranium enrichment plant.
Defense secretary Chuck Hagel calls the development of nuclear weapons "a growing threat to the U.S. and its allies."
The Obama administration is urging North Korea's allies, China and Russia, to find a way to calm tensions, but the U.S. is also making it clear it is ready to respond if necessary.
