The government has demanded that North Korea send Charles Robert Jenkins, a former U.S. soldier married to a returned Japanese abductee, to Japan to treat his illness at a hospital here, Foreign Minister Yoriko Kawaguchi said Friday.

North Korea informed Japan on Thursday that 62-year-old Jenkins has been hospitalized, due to fatigue.

"We are asking (North Korea) to provide us with details (about Jenkins' condition), but they have not responded," Kawaguchi told a news conference Friday morning.
