Iranian state TV says Turkey's prime minister has met with Iranian officials to discuss Syria, where the two nations back opposite sides in the five-year civil war.

Prime Minister Ahmet Davutoglu arrived Friday on a two-day visit, the first by a Turkish official since the lifting of sanctions under a landmark nuclear agreement between Iran and world powers in January.

Davutoglu acknowledged on Saturday that Iran and Turkey differ on Syria, but said cooperation between the two was necessary to end the bloodshed there.

Turkey is a leading backer of the rebels fighting to topple Syrian President Bashar Assad. Iran, along with Russia, has provided crucial support to his government.

Davutoglu said Turkey and Iran hope to expand their trade to $30 billion, triple the current amount.
