Nearly 4,400 further deaths are reportedly under investigation.
In addition, at least 24,266 people have been confirmed arrested in the protests that have shaken Iran since the end of December, according to HRANA figures published on Sunday.
The death toll in Iran varies depending on different organizations' criteria for confirming deaths, and the ongoing internet and telephone blockade makes it even more difficult to obtain information. London-based Iran International has stated that 12,000 people have been killed, while sources cited by several media outlets say the number could be even higher.
On Saturday, Iran's ayatollah admitted that "several thousand" had been killed in the protests - and blamed US President Donald Trump.
