WASHINGTON (Reuters) - U.S. Secretary of State Rex Tillerson spoke on Wednesday with Turkish Foreign Minister Mevlut Cavusoglu and expressed his  profound concern  over the detention of staff at U.S. diplomatic missions in Turkey, the U.S. State Department said in a statement. Tillerson also called on the Turkish government to present evidence behind the accusations against two locally employed staff who were arrested in Turkey this year, the statement said. The detentions prompted Washington to stop issuing visas and triggered a diplomatic crisis.
