Ex-U.S. governor in North Korea with Google chief; seeks American's release

SEOUL (Reuters) - Former New Mexico Governor Bill Richardson and Google Executive Chairman Eric Schmidt began a controversial private mission to North Korea on Monday that will include an effort to secure the release of an imprisoned American.

The trip comes after North Korea carried out a long-range rocket test last month and as, according to satellite imagery, the reclusive state continues work on its nuclear testing facilities, potentially paving the way for a third nuclear bomb test.
