MOSCOW (Reuters) - The United Nations mediator on Syria said moribund peace talks on the conflict could soon be resumed if a faltering truce were extended to the city of Aleppo, something the Russian foreign minister said he hoped would be announced within hours.

Staffan de Mistura, the U.N. envoy, made his upbeat comments on Tuesday after holding talks with Sergei Lavrov, the Russian foreign minister, in Moscow.
