In addition, 500 members of the country's security forces have been killed, according to the news agency. The source describes the Iranian-Kurdish areas in northwestern Iran as among the worst affected by the regime's violent crackdown.
The death toll in Iran varies depending on organizations' criteria for confirming deaths, and the ongoing internet and telephone blockade makes it difficult to obtain reliable information. The US-based organization HRANA had verified just over 3,300 protesters killed as of Sunday, with nearly 4,400 further deaths under investigation.
London-based Iran International has previously stated that 12,000 people have been killed, while sources cited by several media outlets claim that 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.
According to HRANA, at least 24,266 people have been confirmed to have been arrested in the protests, which have shaken Iran since the end of December.
