The Trump administration is expanding its pressure on Iran by imposing new sanctions aimed at the country's missile, drone and oil networks. Treasury announced the move Wednesday that targets 30 people, companies and ships. The sanctions focus on Iran’s “shadow fleet” and on drone makers like Qods Aviation Industries. The measures block access to any U.S.-held property and ban American dealings with those listed. The penalties are part of the Trump administration's efforts to press Tehran to make a deal to further scale back its nuclear program. They were imposed ahead of another round of talks in Geneva on Thursday.
