South Korea says six-party talks at risk if North conducts new nuclear test

SEOUL (Reuters) - South Korean President Park Geun-hye said a fourth nuclear test by reclusive North Korea would render the six-party talks, aimed at reining in the North's nuclear ambitions, meaningless.

In March, the North warned it would not rule out a "new form" of nuclear test to boost its nuclear deterrent, after the U.N. Security Council condemned Pyongyang's launch of a mid-range ballistic missile into the sea east of the peninsula.
