A picture combo shows a screen grab posted on YouTube (L) of Iranian Neda Agha Soltani, who was reportedly killed when hit by a bullet during a protest in Tehran, along with undated pictures of her posted on the Internet on June 22, 2009. A video showing the young woman bleeding to death was put online on June 20 and has since been viewed hundreds of thousands of times around the world. Riot police fired tear gas to break up an opposition rally in Tehran on June 22, reportedly called to pay tribute to Neda, witnesses said, as demonstrators defied a warning from the Revolutionary Guards that it would crush further protests over the disputed presidential election.
