The criminal case against Halkbank moved forward Tuesday as the Turkish state-run bank pleaded not guilty to charges that it had helped Iran evade billions of dollars in U.S. economic sanctions.

In a remote hearing before U.S. District Judge Richard M. Berman of the Southern District of New York, Halkbank’s new defense counsel, Williams & Connolly partner Rob Cary, said his client was prepared to respond to allegations of fraud, money laundering and other sanctions-related offenses laid out in an Oct. 15 indictment.
