ANTALYA, Turkey (Reuters) - Turkish Foreign Minister Hakan Fidan said on Thursday he will discuss the U.S. decision to lift sanctions on Syria and the roadmap ahead in a meeting with his U.S. and Syrian counterparts later in the day. Fidan was speaking to reporters on the sidelines of an informal NATO foreign ministers' meeting in Antalya, Turkey, where he later planned to meet U.S. Secretary of State Marco Rubio and Syrian Foreign Minister Asaad al-Shibani.
