North Korean women line the Pyongyang-Kaesong highway waving red and pink artificial flower bouquets near North Korea’s Arch of Reunification during a march calling for peace and reunification on the Korean Peninsula.

The North Korean women were joined by a group of thirty international women, including two Nobel Peace laureates and feminist icon Gloria Steinem. The group, Women Cross DMZ (WCDMZ), made an historic crossing of the Demilitarized Zone (DMZ) that divides North Korea from South Korea. Together, they walked arm-in-arm with approximately 10,000 Korean women on both sides of the DMZ, calling for a formal end to the Korean War and the replacement of the armistice with a peace agreement.
