Turkey and United States agreed to work together in Syria after weeks of tensions over Ankara’s cross-border operation that raised fears of a confrontation between the two NATO allies. US Secretary of State Rex Tillerson and his Turkish counterpart Mevlut Cavusoglu said after talks in Ankara that the two sides would set up working groups to solve key issues that have bedevilled relations. They gave few details on how this could be achieved, but indicated that solving a dispute over the control of the flashpoint town of Manbij was a priority.
