At least 29 people have been killed during the last 10 days of protests across Iran, a human rights group has said.
The foreign-based Human Rights Activists News Agency (HRANA) reported that two of those confirmed killed as of Monday night were affiliated with security forces. Iranian authorities have not published an official death toll.
HRANA also said 64 protesters had been injured and 1,200 had been arrested during the unrest, which was sparked by an economic crisis and has spread to 27 of 31 provinces.
On Tuesday, videos obtained by BBC Persian showed security forces fired tear gas during clashes with protesters who chanted slogans against Iran's clerical rulers at Tehran's Grand Bazaar.
The protests began on 28 December, when shopkeepers took to the streets of the capital to express their anger at another sharp fall in the value of the Iranian currency against the US dollar on the open market.
