NKorea confirms it has detained an American

North Korea acknowledged Tuesday it had detained an American for illegally entering the reclusive country, news welcomed by relatives of an Arizona missionary who feared they would never hear from him again after he sneaked across the border.

Activists say they last saw Robert Park as he slipped across the frozen Tumen River into North Korea on Christmas Day, carrying letters urging the country's absolute leader to step down and free the hundreds of thousands of people held in political camps. (AP)
