Kazakhstaninfo-icon says delegations from Iraninfo-icon, Russiainfo-icon and Turkeyinfo-icon are arriving in Astana for a third round of talks to put an end to the conflictinfo-icon in Syriainfo-icon.

Kazakh Foreign Minister Kairat Abdrakhmanov said on Monday that delegations had already started arriving despite a request from Syrian militants to delay the meeting. 

The third round of Astana talks is due to take place on March 14-15, with Iran, Russia and Turkey trying to shore up a ceasefire between the warring sides that was brokered in December.

On Monday, Tehraninfo-icon-based mediainfo-icon said the Iranian team had departed for Astana, headed by Deputy Foreign Minister for Arab and African Affairs Hossein Jaberi Ansari.

The first round of the Astana talks took place on January 23-24. The second round was held on February 15-16.

Last week, the militants called for the postponement of the process, saying they had to first make sure about Damascus and its allies' adherence to the ceasefire.

The Astana talks got off the ground after the negotiators successfully mediated an all-Syria ceasefire. The agreement was on the extension of a previous one bringing about a cessation of hostilities in the northwestern Syrian city of Aleppo.
