Tehran's chief prosecutor says authorities have arrested five people on suspicion of spying for the country's "enemies" _ a common reference in Iran for the United States and Israel.
Abbas Jafari Dowlatabadi says the suspects had passed on information to the enemies, including data about Iran's space program, economy and defense.
The prosecutor, whose comments were carried Wednesday by the state IRNA news agency, didn't identify those arrested.
Dowlatabadi accused the U.S. of seeking to gather information on "all fields" in Iran through espionage.
However, he didn't link the arrests to Iran's controversial nuclear program nor to the recent arrest of several people described by Iran's intelligence officials as "nuclear spies."
