North Korea ? Two American journalists seized by North Korean border guards are facing “intense interrogation” in Pyongyang for alleged espionage after illegally crossing into the country from China, a report said Tuesday.

Laura Ling and Euna Lee, journalists working for former Vice President Al Gore’s San Francisco-based Current TV, were at a guesthouse in Pyongyang’s outskirts run by North Korean military intelligence, the JoongAng Ilbo newspaper said, citing an unidentified South Korean intelligence official.

The report provided first word of the women’s whereabouts since they disappeared March 17 during a trip to the border near North Korea’s far northwest. A colleague detained on the Chinese side left China on Tuesday.
