Atomic bomb survivors from Japan are in Norway ahead of the Nobel Peace Prize award ceremony. They handed out paper cranes to Norwegian politicians outside the parliament building in Oslo, together with local children.

About 30 people from Japan gathered outside the building on Monday, ahead of the Tuesday's ceremony where Nihon Hidankyo will be awarded with the peace prize. The Japanese organization is made up of survivors of the 1945 atomic bombings of Hiroshima and Nagasaki.

Their trip to Norway was organized by Japanese NGO Peace Boat and the Japan Council against Atomic and Hydrogen Bombs, also known as Gensuikyo.

They put up a banner reading "No more Hiroshima, No more Nagasaki." Two members of the group -- including survivor Fukushima Tomiko, who experienced the atomic bombing of Nagasaki City when she was six months old -- handed to Norwegian politicians some of the origami cranes they brought from Japan. They say the cranes represent their desire for a world with no nuclear weapons.

Fukushima says she handed out paper cranes on behalf of numerous unnamed victims, in hopes of making the world free of nuclear arms in cooperation with people around the globe.

Local elementary school students joined the Japanese activists, in response to calls from the International Campaign to Abolish Nuclear Weapons, or ICAN. The international NGO won the Nobel Peace Prize in 2017.

The children also put some paper cranes on a Christmas tree outside the parliament building.

ICAN Norway coordinator Tuva Widskjold said she wants Norwegian politicians to listen to atomic bomb survivors. She added that Norway needs to step up its nuclear disarmament efforts and sign the UN nuclear ban treaty.
