The main opposition group at Syrian peace talks in Geneva plans to meet Russian envoys later Monday to discuss promises it says Moscow had not kept, a senior negotiator said.
Russia has sought to revive diplomacy since its air force helped the Syrian army and allied militias defeat rebels in Aleppo in December, President Bashar Assad's biggest victory in six years of war.
Despite a cease-fire, a weekend of bombings and airstrikes in Syria has rattled the talks that began in Geneva last week.
"The (opposition) High Negotiations Committee (HNC) will be meeting today with the delegation of the foreign ministry," negotiator Mohammed Alloush told Reuters when asked if he planned to meet Russian officials.
He said the opposition wanted to discuss "the promises they did not keep."
