North Korea's official news agency says a U.S. State Department delegation led by Robert King left North Korea on Saturday.

The Korean Central News Agency briefly announced that U.S. Special Envoy for North Korean Human Rights Issues Robert King and his delegation left the country after visiting the North to discuss bilateral humanitarian concerns.

But the report didn't say if recently freed Korean-American detainee Jun Young-su left the North with King. Pyongyang had been holding the U.S. citizen since November and announced Friday that it will be releasing him.

In North Korea, the U.S. team led by King held on-site inspections to survey the food demand and met with Pyongyang officials.

Based on the results, Washington will decide whether to resume food aid to the North.

Some U.S. experts who accompanied King to North Korea will remain there until early June to continue inspections.
