Iran says Iranian-Canadian scientist passed information to CIA, Mossad
The report said Kavous Seyed-Emami, a university professor, was in custody for passing information on the country's missile bases to the CIA and Mossad and planning to create environmental crisis.
The report didn't elaborate.
IRNA quoted Tehran prosecutor Abbas Jafari Dolatabdi as saying Seyed-Emami and a network of people installed cameras in strategic areas of the country pretending to observe environmental issues but, in fact "it was for monitoring the country's missile activities and they were sending images and information to foreigners."
Dolatabdi said Seyed-Emami hosted one of two US intelligence officers during their visit to Iran.
He didn't elaborate.
On Monday, Iran said Seyed-Emami took his own life.
But the family of the environmentalist who died in an Iranian prison called for a post-mortem, rejecting claims by officials that they had accepted the explanation of suicide.
"The family has put in a request for a post-mortem," Arash Keikhosravi, lawyer for the family of Iranian-Canadian Kavous Seyed Emami, told the reformist Shargh newspaper.
Emami's family were informed on Friday that the renowned professor and founder of the Persian Wildlife Heritage Foundation had died in custody just over two weeks after being arrested on espionage charges.
