Female activists from around the world will march from Pyongyang to Seoul in May to express their wish for inter-Korean peace, a global non-profit said Sunday.

The Peace Development Fund said around 30 female activists will be participating in the march, which will see them cross the heavily fortified Demilitarized Zone bisecting the Korean Peninsula, on May 24.

The activists include American feminist Gloria Steinem, Nobel Peace Prize laureate Mairead Maguire and Chung Hyun-kyung, a professor at Union Theological Seminary in New York, the organization said.

"Our wish is to cross the DMZ, which separates tens of millions of Korean families, on foot to express our hope for peace," the group said in a statement.

Participants will also hold peace seminars in the two Korean capitals and discuss the role of women in reducing inter-Korean tension.

The two Koreas are technically at war since the Korean War in the 1950s ended in an armistice, not a peace treaty. (Yonhap)
