Tensions continue to rise with North Korea, but the question remains whether the young leader Kim Jong Un thinks he can get away with an attack on the South. David Martin reports.

SEOUL (Reuters) - North Korea announced plans on Tuesday to restart a mothballed nuclear reactor that has been closed since 2007, but emphasized it was seeking a deterrent capacity, rather than repeating recent threats to attack South Korea and the United States.

The state-owned KCNA news agency said North Korea would restart all nuclear facilities for both electricity and military uses.
The announcement came amid soaring tensions on the Korean Peninsula as the United States bolstered its forces in the region after a series of threats by Pyongyang to attack U.S. bases in the Pacific and to invade South Korea.

North Korea, one of the most isolated and unpredictable states in the world, conducted its third nuclear test in February but is believed to be some years away from developing nuclear weapons, although it claims to have a deterrent.
