The report did not specify how the deaths occurred, but state television reported earlier that several people were killed Saturday when "rioters" attacked a mosque in western Tehran.

Sunday's report on Iran's official English language station said "rioters" set two gas stations on fire and attacked a military post.

Iran's capital was wracked by violence Saturday as security forces clashed with supporters of Mir Hossein Mousavi, who claims he won the June 12 presidential election.

The report was the second confirmation of deaths since unrest began. State media said seven people were killed early in the week.
