Almost 650 protesters have been killed by Iranian security forces in anti-government demonstrations that have swept Iran since the 28 December, according to one human rights group.
But sources in Iran have told the BBC the death toll is likely to be higher than reported.
Coach Amir Mohammad Koohkan, 26, and student Rubina Aminian, 23, are among hundreds of protesters reportedly killed during two weeks of protests in Iran.
Iranian authorities accused the US and Israel of fomenting trouble and condemned "terrorist actions", state media reported.
Internet access has been cut by the authorities, making reporting from Iran more difficult than ever. BBC Persian is banned from reporting inside Iran by the government.
