Korean lawmakers are seeking the Vatican's help in resolving the issue of the former comfort women.
According to Rep. Kim Hyun-sook of the ruling Saenuri Party, a petition signed by members of the Catholic lawmakers' association requesting the international community's support on the issue will be delivered to Pope Francis through the Vatican's Embassy to Korea.
Along with the Korean lawmakers, David Alton, a member of the UK's House of Lords, and 36 other legislators from 20 nations including Italy and the US also signed the petition.
The term "comfort women" refers to those who were forced to work as sex slaves for the Japanese military during the first half of the 20th century.
With Japanese lawmakers and historians continuing to deny that the government of the time was involved in the issue, local lawmakers have been seeking international cooperation for some time.
In August, Reps. Hong Il-pyo of the ruling party and Kim Jae-yun of the main opposition Democratic Party, who are also members of National Assembly's Catholic lawmakers' association, called on the International Catholic Legislators Network to support their cause.
