North Korea to cut ties with South

May 25) -- North Korea, blamed for the deadly sinking of a South Korean warship, said today it will cut all ties to the South and expel South Koreans working north of the border in a further escalation of tensions on the Korean Peninsula, according to reports.

The official Korean Central News Agency said late today that the North's actions were punishment for what it called a "smear campaign" over the sinking, The Associated Press reported.

Someday - sooner rather than later - someone is going to have to call North Korea's bluff.
