For generations journalists have risked their lives and given their lives – covering wars, human disasters and uncovering dark and ugly crimes.
Over the past several years the targets of these stories have increasingly turned their guns on the truth-seekers: the journalists.
Exactly one year ago veteran foreign correspondent Marie Colvin – a legend in journalism – was killed by a shelling attack in Syria. French photographer Remi Ochlik was killed alongside her.
British photographer Paul Conroy, who survived that attack, says he is sure they were specifically targeted.
The Committee to Protect Journalists says 70 journalists were killed in 2012, a 49% increase from the previous year.
232 journalists are imprisoned around the world and 35 are missing.
A new campaign called "A Day Without News" is trying to raise awareness and bring penalties to those who target journalists.
One of the leading voices in that campaign belongs to New York Times photographer Lynsey Addario.
In the video above CNN’s Christiane Amanpour speaks with Addario about the campaign and discusses how she and three of her colleagues were abducted while covering the Libyan revolution and held for six terrifying days.
