Moscow claims strikes had been coordinated with Turkey, but Ankara denies that Some experts see the bombing as a sign that Moscow is turning the screw on Erdogan ANKARA: An escalation of heavy air and artillery strikes on Idlib in northwestern Syria on Wednesday night has raised doubts over the future of the Astana deal between Turkey, Russia and Iran. Moscow claimed the bombing of Syria’s last rebel stronghold had been coordinated with Turkey, but this was denied by Ankara. Under the deal, Turkey was expected to persuade rebel groups to remove heavy weaponry from a designated buffer zone, and convince hard-line groups, including Al-Qaeda affiliated Hayat Tahrir Al-Sham (HTS), to withdraw completely from major highways as part of a “de-escalation” process. But HTS fighters remain in place, controlling 80 percent of the region, and criticism of Ankara for failing to honor its part of the agreement is becoming more acute. Some experts see the bombing as a sign that Moscow is turning the screw on Turkey’s President Recep Tayyip Erdogan, either to assume more responsibility or renegotiate the terms of the deal. Turkey had already been discussing extending patrols to Tal Rifaat, in northern Aleppo, with the Russians after Defense Minister Hulusi Akar announced similar cooperation would happen in Idlib. “Perhaps Moscow is trying to raise the stakes to get constructive talks with Ankara on Idlib and find a solution to the future of HTS,” Anton Mardasov, military affairs expert and head of the Department of Middle Eastern Conflicts at the Moscow-based Institute for Innovative Development, told Arab News. “It’s not profitable for Ankara to confirm the coordination of strikes with Moscow, though the strikes can be used by Turkey to increase pressure on HTS to accept their terms. “Negotiations will be beneficial for Russia, to demonstrate a successful Syrian strategy. For Turkey, it is also an opportunity to advance its agenda, although Ankara has long been thinking about balancing its position by intensifying negotiations with its European partners in NATO.” Turkey is also discussing establishing a joint coordination center in Idlib to manage operations at the behest of the Kremlin, which has criticized Ankara’s lack of engagement in recent months. “If there is no political progress, Russia always resorts to hard power moves to motivate their partners. That’s how they will push Turkey to do more,” Yury Barmin, Middle East and North Africa director at the Moscow Policy Group, told Arab News. “These attacks are happening against the background of the EU Conference on Syria in Brussels. The Russians are trying to put Syria on the radar of the Europeans to intervene,” he added. According to Joe Macaron, a resident fellow at the Arab Center in Washington, Ankara may have approved Russian operations against HTS, but would be reluctant to let its allies believe it was complicit in them. “With the current tensions in US-Turkish relations, Ankara has no option but to manage its marriage of convenience with Moscow,” he said.
