Police will put two wives of Red Army Faction hijackers living in North Korea on an international wanted list, possibly later this month, on suspicion they were involved in the abductions of two Japanese nationals from Europe to the North in 1980, according to investigation sources.

The two are Yoriko Mori, 53, and Sakiko Wakabayashi, 60, both of whom are already wanted for violating the passport law.

Mori married Takamaro Tamiya, leader of the Red Army Faction hijackers who forced a Japan Airlines airplane to land in North Korea in 1970. Tamiya died in 1995. Wakabayashi is the wife of Moriaki Wakabayashi, 60.
