Bosnia and Herzegovina marked White Ribbon Day on Wednesday in honor of more than 3,000 civilians killed in the western town of Prijedor.
Thousands in Prijedor and across the country wore white ribbons on their arms to mark the 31st anniversary of the massacre.
A crowd gathered in the center of Prijedor and urged authorities to build a monument in memory of 102 children who were killed.
Fikret Bacic from the Association of Families of Children Murdered in Prijedor said the bodies of 640 people in Prijedor have not yet been found.
On May 31, 1992, the Serbian administration in Prijedor ordered the non-Serb population to wear white stripes on their arms when they left their houses. It was an order that was followed by extermination, murder and persecution.
More than 100,000 people were killed in the war, while 2 million were uprooted from their homes.
The country suffered greatly during its war of independence, which included the siege of Sarajevo and the genocide of Srebrenica -- Europe's worst wartime atrocity since 1945.
