(CNN) -- The Dalai Lama and other Nobel laureates on Friday met in the Japanese city of Hiroshima to call for an end to nuclear weapons.
Hiroshima was hit by the world's first atomic bomb attack in 1945.
It's the first time the annual three-day event has been held in Japan.
During the event, the laureates paid tribute to other winners and called for the release of jailed Chinese dissident Liu Xiaobo, winner of the 2010 prize.
The annual meeting of Nobel Peace laureates focuses on the award's message of nonviolence.
Other attendees included former South African President F.W. de Klerk and Jody Williams, a 1997 recipient for her work to eliminate landmines.
Mikhail Gorbachev, the former Soviet Union leader, did not attend for health reasons, event spokesman Pio d'Emilia said.
Gorbachev won the award in 1990 for helping end the Cold War.
U.S. President Barack Obama, who won last year, was in South Korea for the G-20 summit.
The U.S. dropped the bomb on Hiroshima on August 6, 1945, near the end of World War II.
A few days later, another bomb struck Nagasaki.
The bombs devastated both cities and killed more than 200,000 people.
