For more than 40 years, the Turkish government has fought the PKK in eastern Turkey, northern Iraq and Syria. Recent efforts to establish a ceasefire between the Turkish government and the PKK raise new hopes for stability in the Middle East.

Turkey is "cautiously optimistic" about an agreement between the Kurdish-led and U.S.-backed Syrian Democratic Forces (SDF) and Syria's new government, a Turkish official said on Tuesday, adding Ankara wanted to first see how it would be implemented.

Syria's interim government said it has reached a landmark agreement to integrate Kurdish-led forces into state institutions as it continues to try to unify the country following years of civil war.
