Two US journalists captured by North Korea while working on the wrong side of the border with China have been taken to the capital and are being "interrogated," Reuters reports. The two female reporters were working for Al Gore's cable channel, Current TV. Full diplomatic efforts are under way to secure their release. The experience of the last American arrested by North Koreans does not bode well for the duo: It took three months to free him. The situation only adds to the tension surrounding North Korea's preparation for a missile launch.
