S. Korea demands talks with N. Korea on closed factory

South Korea on Thursday warned of unspecified "grave measures" if North Korea rejects talks on a jointly run factory park shuttered for nearly a month - setting up the possible end of the last remaining major symbol of inter-Korean cooperation.

The demand for talks, which is likely to draw an angry response from North Korea, follows a lull in what had been a period of rising hostility between the Koreas. Pyongyang has recently eased its threats of nuclear war and expressed some tentative signs of interest in dialogue, and Washington and Seoul have also pushed for an easing of animosity. (AP)
