"There is a working group on the Syria de-escalation zones. Last week, [Alexander] Lavrentyev, the envoy of [Russian President Vladimir] Putin for Syria, was here. We had detailed negotiations with him," Kalin said as quoted by the Haberturk channel.
The group is still working on the de-escalation zones map with demarcation lines, the spokesman said.
"A mechanism is being developed within the framework of which our and Russian servicemen could maybe be in Idlib, Russian and Iranian [servicemen] near Damascus, Jordanian and US [servicemen] south of Daraa," he added.
"There was even a proposal from the Russians to send a certain number of Kyrgyz and Kazakh [servicemen]. They too can take their place in the framework of these efforts… but all this requires detailed work," Kalin said.
