Lavrov did not say where the current talks were being held.
President Vladimir Putin has that Russia, Iran, Turkey and regime leader Assad have all agreed that the Kazakh capital should be the venue for new Syrian peace negotiations.
The RIA news agency cited an unnamed diplomatic source earlier on Tuesday as saying that representatives from the Russian and Turkish militaries were holding consultations with the Syrian opposition in Ankara about how a possible nationwide ceasefire might work.
