N.Korea threatens rival South over UN sanctions AFP 1/25/2013 4:07:34 AM North Korea on Friday threatened "physical counter-measures" against rival South Korea -- the latest in a series of bellicose warnings sparked by a tightening of UN sanctions against Pyongyang."If the South Korean puppet regime of traitors directly participates in the so-called UN 'sanctions', strong physical countermeasures would be taken," the North's Committee for Peaceful Reunification of Fatherland said.The warning, carried by the official Korean Central News Agency, came a day after North Korea threatened to conduct its third nuclear test and boost its capacity for a military strike on the United States."Sanctions amount to a declaration of war against us," said the committee, which is the prime state body responsible for inter-Korean dialogue and exchange. While Thursday's threat had firmly targeted the United States, the latest warning focused Pyongyang's anger on the capitalist South."As long as the South Korean puppet traitors' regime continues with it's anti-DPRK (North Korea) hostile policy, we will never sit down with them," it said.
