GENEVA (Reuters) - Talks between U.S. and Russian officials this week are crucial for restoring a ceasefire in Syria, the United Nations Special Envoy Staffan de Mistura said in an appeal on Tuesday.
U.S. Secretary of State John Kerry and Russian Foreign Minister Sergei Lavrov failed in all-day talks in Geneva last Friday to reach a breakthrough deal on military cooperation and a nationwide cessation of hostilities, saying they still had issues to resolve.
