According to Anadolu, Yildirim and Jahangiri discussed the latest developments in Syria and Iraq, and other regional and international issues during the closed-door meeting at Cankaya Palace, a prime ministry source said.
"We appreciate and care about Iran's close cooperation in conducting an effective fight against PKK terrorist group which has been a headache for Turkey for the last 40 years," Yildirim told a joint press conference with Iran’s First Vice President Eshaq Jahangiri in the capital Ankara.
Jahangiri is scheduled to attend the Developing-8 Countries (D-8) meeting in Istanbul on Friday.
The ninth summit marks the 20th anniversary of the economic group consisting of eight emerging economies from the Muslim world.
The organization was established on June 15, 1997 by Turkey, Indonesia, Bangladesh, Egypt, Iran, Malaysia, Nigeria and Pakistan.
Today, the organization has a combined GDP of $3.7 trillion and includes more than one billion people -- around 15 percent of the world’s population.
