AP - Iran sentenced eight environmental activists, including an Iranian who reportedly also has British and American citizenship, to prison sentences ranging from four to 10 years on charges of spying for the United States and acting against Iran's national security, the judiciary said Tuesday.

According to the judiciary spokesman, Gholamhossein Esmaili, an appeals court issued the final verdicts.

Two of the activists, Morad Tahbaz and Niloufar Bayani, got 10 years each and were ordered to return the money they allegedly received from the U.S. government for their services.

Tahbaz is an Iranian who also holds U.S. and British citizenship.

Iran does not recognize dual or multiple nationalities, meaning Iranians it detains cannot receive consular assistance from their other countries. In most cases, dual nationals have faced secret charges in closed-door hearings before Iran's Revolutionary Court, which handles cases involving alleged attempts to overthrow the government.
