Iran's judiciary says it has sentenced an American citizen to 10 years in prison for allegedly "infiltrating" the country and gathering information.

Judiciary spokesman Gholamhosein Mohseni Ejehi announced the sentence during a briefing to reporters Sunday.

He did not provide details on the suspect's identity, saying only that the person was a dual national holding American citizenship and that of another country.

Ejehi says the verdict can be appealed.
