Washington, July 9 - The next time you surf the internet, you may bump into a Nobel Peace Prize candidate. A US security expert has proposed the honour for micro-blogging site Twitter, which helped protesters in Iran beat censorship and tell their tale to the world.

The free social-messaging utility uniquely documented and personalised the story of hope, heroism and horror in Iran, says Mark Pfeifle, former deputy national security adviser for strategic communications and global outreach at the US National Security Council.

'The video gave substance to what seemed so far away. We saw the look in her eyes as they went lifeless. We heard the sounds of her friends and family as they begged her to hold on. And she became the personification of the struggle for democracy in a country where voices for freedom are quelled,' Pfeifle wrote in The Christian Science Monitor this week.

'Her name was Neda Agha-Soltan, and without Twitter we might never have known that she lived in Iran, that she dreamed of a free Iran, and that she died in a divided Iran for her dreams.'

'Neda became the voice of a movement; Twitter became the megaphone. Twitter is a free social-messaging utility. It drove people around the world to pictures, videos, sound bites, and blogs in a true reality show of life, dreams, and death. Last month's marches for freedom and the violent crackdowns were not only documented but personalised into a story of mythic tragedy.'

The article titled 'A Nobel Peace Prize for Twitter?' notes that when journalists were forced to leave iran, Twitter became a 'window for the world to view hope, heroism, and horror. It became the assignment desk, the reporter, and the producer. And, because of this, Twitter and its creators are worthy of being considered for the Nobel Peace Prize.
