The unnamed people who captured on video the shooting death of an Iranian protester have won a prestigious journalism prize, the first time it has been awarded anonymously.
Music student Neda Agha-Soltan was gunned down during protests over Iranian President Mahmoud Ahmadinejad's disputed re-election.
Footage of her death was seen by millions of people and became "an iconic image of the Iranian resistance", the curator of the George Polk Awards said.
The film made Neda's name a rallying cry for the opposition and sparked international outrage at the harsh response of security forces.
"This award celebrates the fact that, in today's world, a brave bystander with a cell (mobile) phone camera can use video-sharing and social networking sites to deliver news," said award curator John Darnton.
The Polk Awards, presented by Long Island University, are considered among the top prizes in US journalism.
