Protester death toll in Iran passes 500, US-based rights group says

From CNN's Billy Stockwell

At least 503 protesters have been killed in just over two weeks of anti-government demonstrations in Iran, according to US-based Human Rights Activists News Agency (HRANA).

It remains unclear whether HRANA’s tally fully captures the scale of casualties, given the authorities’ shutdown of internet access and telephone lines.

CNN is unable to independently verify HRANA’s death toll.
