“An Iranian court has upheld the conviction and 10-year jail sentence of a US man accused of spying. Chinese-American Xiyue Wang was imprisoned in July for ‘collaborating with foreign governments’ – a charge he denies. He was arrested while doing research in Iran for a university dissertation. Three others facing similar charges have also had their jail sentences upheld. Two have joint US-Iranian citizenship, and one is Lebanese.”
