Laura Ling and Euna Lee were arrested on March 17 near the Tumen River, which runs along the border between North Korea and China, while reporting on North Korean refugees for San Francisco-based Current-TV.

North Korea has accused them of illegally entering its territory with "hostile" intent.

The Associated Press reports the journalists could face at least five years in prison if they are convicted of espionage under North Korean law.
