( CNN ) -- Iran has hanged a man convicted of spying for Israel and also executed another man who was a member of a government opposition group , state-run media reported Tuesday . The executions took place at Tehran 's Evin Prison at dawn Tuesday . Ali-Akbar Siadat was sentenced to death for working as a spy for Israeli intelligence . The Islamic Republic News Agency said Siadat admitted to transferring information to Israel over several years in exchange for $ 60,000 . He was arrested in 2008 while trying to leave Iran along with his wife , the news agency said . A second man , Ali Saremi , was hanged for `` fighting against the sacred Islamic Republic of Iran system and launching antagonist propagations , '' the agency reported . He was a member of People 's Mujahedeen of Iran , also known as the Mojahedin-e Khalq Organization , which has opposed the Iranian government for decades . Tehran considers the group to be a terrorist outfit , as does the United States . The European Union does not . Members of a European Parliament group , Friends of a Free Iran Intergroup , condemned Saremi 's execution Tuesday , calling it `` another crime for which the mullahs will be held to account when freedom is finally restored to that beleaguered nation . '' The group also demanded that Iranian leaders `` be tried in the International Court of Justice for crimes against humanity . '' CNN 's Mitra Mobasherat contributed to this report .
