The UN's Syria envoy will meet ambassadors from the five permanent members of the United Nations Security Council on Wednesday in Geneva, ahead of planned talks to end the country's civil war, a statement said, according to AFP.

Envoy Staffan de Mistura has been trying to secure support for a fresh round of negotiations, which are provisionally scheduled to start on January 25, and are aimed at resolving the brutal conflict.

His meeting with Britain, China, France, Russia and the United States will be "at the ambassadorial level," and will take place at the UN's European headquarters in Geneva, UN spokesman Ahmad Fawzi said.
