平壤声称将重新启动宁边核设施

North Korea says it is restarting all operations at a shuttered nuclear reactor, adding to already heightened tensions on the Korean peninsula.

The official Korean Central News Agency quoted officials as saying Pyongyang would "readjust and restart" the facilities at the Yongbyon complex both to build more bombs and address the country's electricity shortage.

It said this will include a uranium enrichment plant and a five megawatt reactor that can generate spent fuel rods laced with weapons-grade plutonium. The reactor was shut down in 2007 in exchange for economic aid.

The move follows weeks of  threats by Pyongyang, which is angry at tough United Nations sanctions passed in response to its third nuclear test and latest satellite launch.
