Turkey’s foreign minister says Ankara is closely monitoring an agreement between the Syrian government and a U.S-backed Kurdish-led armed group.

The agreement marked a major victory for Damascus in its quest to unify the country, as violent unrest continues to grip Syria’s coastal region.

It was a development in the Syrian drama almost as unexpected as the stunningly swift fall of the Assad regime that had dominated this country for decades.

Turkey’s top diplomat, defense minister and intelligence chief paid a sudden visit to Damascus. The visit Thursday comes days after Syria’s interim government reached a deal to integrate a U.S backed Kurdish-led armed group,

The deal would allow Kurdish-led forces which hold a quarter of Syria to merge with Damascus, along with regional Kurdish governing bodies.

Syria’s interim government says it has reached a landmark agreement with the Kurdish-led Syrian Democratic Forces (SDF) to integrate the group into state institutions.

The scenes of elation following Monday night's declaration came in sharp contrast to the grim scenes in coastal communities wracked by days of clashes.

Turkish President Tayyip Erdogan welcomed an agreement between the Kurdish-led and U.S.-backed Syrian Democratic Forces (SDF) and Syria’s new government, saying its full implementation would contribute to security and stability in the country.
