ANKARA (Reuters) - Turkey did not violate U.S. sanctions against Iran and  did the right thing  regardless of the outcome of the ongoing case in the United States, President Tayyip Erdogan was quoted by private broadcaster CNN Turk as saying on Thursday. On Wednesday, Turkish-Iranian gold trader Reza Zarrab described in a U.S. court how he ran a sprawling international money laundering scheme aimed at helping Iran get around U.S. sanctions and spend its oil and gas revenues abroad, in a case that has further strained ties between Ankara and Washington.
