The displeasure was expressed in an article by the daily on Sunday, which said the road map” for Syria’s Idlib province and the ceasefire agreement between and Ankara and Moscow remained “unclear.’’

Moscow and Ankara remain at odds over a number of issues, including Syria, where they support opposing camps.

In March 2020, Turkey and Assad regime-backer Russia reached a ceasefire following weeks of violent fighting in northwestern Idlib province. Eighteen months later, both Turkey and Russia have complained about repeated violations of the truce in the region.

The two leaders on Wednesday held talks in the Russian Black Sea resort of Sochi on curbing renewed violence in northwest Syria and on possibly expanding Russia's sales of military defense systems to Ankara despite NATO and U.S. objections.

There were evident “differences” in the summit, it cited Al Watan as saying, referring to Russian airstrikes on opposition territory and Turkish-backed rebel groups firing on regime forces in Idlib.

Al Watan also voiced “frustration over fortifications along the M4 and M5 highways to prevent a regime advance,’’ it said.

Turkey and Russia had also agreed in March 2020 to launched a joint patrolling mission along the key M4 highway, which links Aleppo to Latakia.
