PAJU, South Korea (Reuters) - North Korea said it was kicking out all South Koreans from the jointly run Kaesong industrial zone on Thursday, calling the South's move to suspend operations, in retaliation for Sunday's rocket launch by the North, a "declaration of war".

The North declared the industrial park, run by the rivals as a symbol of cooperation for more than a decade, a military control zone, the agency that handles its ties with Seoul said, according to the official KCNA news agency.
