Fresh talks on the Syria conflict will be held in Astana at the end of the month, Kazakhstan said Thursday, as part of a Turkey-backed push to end the six-year conflict.

The two-day meeting, which will take place Oct. 30-31 in the Kazakh capital, will be the seventh round of negotiations this year that are co-sponsored by regime backers Russia and Iran and opposition supporter Turkey.

"The guarantor states of the cessation of hostilities have agreed that the seventh round of high-level talks on Syria as part of the Astana process will be held on October 30-31," the Kazakh foreign ministry said in a statement.

The talks promote gradual cease-fires and de-escalation zones. At the last set of talks in September, the three powers agreed to allocate forces to patrol the zone covering opposition-held Idlib province and neighboring regions.

On May 4, Russia, Turkey and Iran signed a deal in the Kazakh capital Astana to establish de-escalation zones in Syria.

The May 4 de-escalation zone agreement envisages the halt of hostilities between Assad regime forces and moderate opposition groups within the zones as well as the creation of conditions for humanitarian access, medical assistance, the return of displaced civilians to their homes and the restoration of damaged infrastructure.

The guarantor states previously agreed to take all measures necessary to continue fighting Daesh, al-Nusra and other terrorist groups both within and beyond the de-escalation zones.

Syria's conflict evolved from a bloody crackdown on protests in 2011 to a devastating war that has drawn in world powers, including Russia and a U.S.-led international coalition. Since then, more than 250,000 people have been killed and in excess of 10 million displaced, according to the U.N.

The diplomatic push brings together the Assad regime and representatives of the opposition, including some key armed groups who had previously steered clear of other negotiations.

Moscow has been spearheading the talks in a bid to pacify Syria after its game-changing intervention on the side of the regime.
