Turkey and Saudi Arabia are strong backers of the rebels fighting to overthrow Syrian President Bashar Assad, who is supported by Russia and Iran.

Erdogan said his government and Saudi Arabia are working "in solidarity and consultation" to find a political solution for Syria, as both countries push for an agreement that would remove Assad from power.

The two sides were expected to discuss energy cooperation as Ankara works to diversify its supplies following a rift with Moscow over the downing of a Russian plane.

The Saudi Press Agency confirmed the two leaders discussed the conflicts in Syria and Iraq, as well developments in war-torn Libya and Yemen, where Saudi forces are battling Shiite rebels.

Russia began airstrikes in Syria on September 30, saying it wanted to support the Syrian government and defeat Islamic State militants and other extremists.

But many of the strikes have hit Western-backed rebel groups in areas where IS is not present, and Syrian activists say the Russian strikes have killed civilians.
