Secretary of State Hillary Rodham Clinton says she is "incredibly concerned" about the plight of two U.S journalists on trial in North Korea.
Clinton said Friday she considered the trial "a step toward the release and the return home of these two young women."
She calls on the North to immediately let the women go.
In working for their release, Clinton says she has spoken with foreign officials with influence in North Korea and has explored the possibility of sending an envoy to the North.
But she suggested that no envoy would be sent during the trial.
There have been no updates of the criminal proceedings that were supposed to begin Thursday for TV reporters Laura Ling and Euna Lee.
