From the BBC:

The Associated Press (AP) news agency has been reporting news and transmitting pictures since 1846, in the earliest days of the long-distance telegraph.

As the agency publishes Breaking News, a history of its role reporting war and peace around the world, the BBC asks three AP photographers - Horst Faas, a two-time Pulitzer Prize winner most famous for his work during the Vietnam War, Santiago Lyon, AP's current global director of photography, and Oded Balilty, an Israeli who won a 2007 Pulitzer Prize for breaking news photography - for their views on the dangers of carrying cameras in conflict (audio slideshow).
