Several environmental scientists have been arrested in Iran and accused of spying on nuclear facilities. One of the scientists, an American citizen Morad Tahbaz, graduate of Columbia University, is co-founder of the Persian Wildlife Heritage Foundation. Members of the Foundation have openly opposed installation of underground nuclear and missile launch facilities on protected lands. Its managing director, Canadian citizen Kavous Seyed-Emami, detained last January together with Morad Tahbaz and seven others, died in Evin prison after intense interrogations soon after his arrest.
