In an open letter published in several newspapers, some 50 leading figures urged Russia to use its influence in Syria to push for an "Olympic truce" in the country's conflict.
"If the Olympic Games showcases the best of humanity, Syria showcases the worst. The most expensive Games in history will take place so close to the worst humanitarian crisis of our times," said the letter, published in Le Monde, The Financial Times and Russian newspaper Novaya Gazeta.
The letter also called on Russia to lead efforts in the UN Security Council to ensure local ceasefires and the delivery of humanitarian supplies. It also urged continued Russian support for peace efforts to resolve the conflict.
