The chairman of the U.S. Senate subcommittee on East Asian and Pacific affairs on Monday told the families of Japanese nationals abducted by North Korea that the U.N. Security Council should take up the issue as a question of human rights.

The families met with Sen. Sam Brownback in their efforts to win the support of the international community.

The Japanese included Shigeru Yokota, 70, who heads a liaison group for Japanese families with relatives who were abducted by North Korean agents, and his wife, Sakie, 66.
