The United States has still not received any response from North Korea to its continuing efforts to make contact about Private Travis King, State Department deputy spokesperson Vedant Patel said, despite Pyongyang’s state media acknowledging for the first time on Wednesday the U.S. soldier’s crossing from South Korea.

“We have raised this case through the appropriate channels that exist to send messages and communicate to the DPRK,” Patel said at a regular press briefing, referring to the Democratic People’s Republic of Korea.
