TEHRANinfo-icon -- Leaders of Russiainfo-icon, Turkeyinfo-icon and Iraninfo-icon on Friday discussed a step-by-step "stabilisation" in Syriainfo-icon's Idlib, with a possibility of peace with some rebel groups, Russian President Vladimir Putin said after the talks.

"We have discussed concrete measures regarding a phased stabilisation in the Idlib de-escalation zone, which stipulate... a possibility of making peace for those ready for dialogue," Putin said after the summit in Tehran to discuss the fate of Syria's last rebel bastion.

Putin said that Russia hopes that its "call for peace in Idlib zone as well will be heard... we will strive for peace among all warring sides, and we have never factored in terrorist organisations."

"We hope that representatives of terrorist organisations will have enough common sense to stop resistance and lay down (their) weaponsinfo-icon," Putin said.

Turkey seems to have prevailed during talks, convincing the other parties that a major offensive in Syria's Idlib province would not be the wisest move at the moment.

At Erdogan's suggestion, the final communique of the summit was amended to include a call for all armed groups in Idlib to lay down arms and seek a political transition in the country.

Putin and Rouhani agreed, which may indicate that a major offensive in Idlib is not likely to be launched in the immediate future, unless some major development happens on the ground.

The Russian president remarked that the call is addressed to all armed groups in the Syrian province, including UN-designated terrorist groups.

"Let usinfo-icon hope that the members of the terrorist organizations would have enough sense to stop resistance and lay down weapons," he said.

"Our agreements on Syria were always based on a premise that we are seeking to ensure peace between all belligerents, but kept the terrorist organizations bracketed out," he remarked.
