In a stinging snub to the US, Turkish President Recep Erdogan refused to receive Vice President Mike Pence and Secretary of State Mike Pompeo who were due to visit Ankara on Thursday. “I only talk to President Trump,” he said. They were to head a large delegation to relay President Trump’s demand that Turkey pull back from Syria and negotiate a truce – or face economic sanctions. Other members were national security adviser Robert O’Brien and Special envoy to Syria James Jeffrey. Erdogan earlier announced that Turkish forces would not back down from their Syrian operation and rejected Trump’s demand for a truce. The Turkish and Russian presidents talked by phone on Tuesday and arranged for Erdogan to visit Moscow later this month and discuss averting a clash between Turkish and Syrian forces.
