North Korea has told an unofficial U.S. delegation that it is prepared to allow the 16-year-old daughter of Japanese abductee Megumi Yokota to travel to Japan with the families of five repatriated Japanese abductees, a source close to the delegation said Friday.

In talks between Japanese lawmakers and North Korean officials in Beijing in late December, North Korea said it would allow the relatives of the five repatriated Japanese abductees to go to Japan if they first travel to Pyongyang airport to meet their families.

The source said two U.S. Senate foreign aides, who traveled to North Korea recently as members of the unofficial U.S. delegation, discussed the proposal with Song Il Ho, a vice director of the North Korean Foreign Ministry.

Song told the Senate aides that the proposal includes "all of the family members" and that North Korea did not exclude Yokota's daughter, Kim Hye Gyong, the source said.
