Ankara views the YPG as a terrorist offshoot of the Kurdistan Workers' Party (PKK), an insurgency in Turkey which is listed as a terror organisation by the US and the European Union. But in Syria, Washington has been providing arms to the YPG against the Islamic State group, much to Ankara's chagrin in a dispute that has ignited the biggest crisis in bilateral ties since the 2003 US-led invasion of Iraq.
The US has previously called on Ankara for restraint and said operation "Olive Branch" risked becoming a distraction from the fight against jihadists in Syria. The renaming of the street follows a visit by US Secretary of State Rex Tillerson to Ankara last week when he met Turkish officials including President Recep Tayyip Erdogan and the two sides agreed to cooperate in Syria.
"We are not going to act alone any longer, not US doing one thing, Turkey doing another," Tillerson said after talks with Turkish counterpart Mevlut Cavusoglu. The two sides said they would set up working groups to solve key issues affecting relations. Ankara mayor Mustafa Tuna mooted the plan to change the name from Nevzat Tandogan (a former Ankara governor) to Olive Branch avenue before Tillerson arrived on Thursday.
City workers switched the actual signs on Monday. Although the American embassy is located on what is now Olive Branch avenue, the mission's official address is given as the street behind the building, which is named after Ataturk, the founder of the Turkish republic.
