CORRECTION: An earlier post incorrectly stated the number of photographers killed.
Photographer and Oscar-nominated director Tim Hetherington was killed amid fighting in the Libyan city of Misurata on Wednesday, according to various media reports citing colleagues. Three other photographers were wounded, one fatally.
Chris Hondros, who suffered a severe brain injury, died a few hours later. Guy Martin was seriously injured, a colleague who was with them at a triage center on Wednesday night told The New York Times. Hondros and Martin work for photo agencies Getty and Panos, respectively.
Another photographer, Michael Christopher Brown, suffered injuries but is expected to survive, according to the Times.
Hetherington produced pieces from Afghanistan for ABC News's Nightline and co-directed Restrepo, an award-winning documentary about a platoon in one of Afghanistan's most dangerous areas.
In his last post on Twitter at 6:46 a.m. on Tuesday, Hetherington shared his whereabouts: "In besieged Libyan city of Misrata. Indiscriminate shelling by Qaddafi forces. No sign of NATO."
Hondros has reported on conflicts from Kosovo to Lebanon, Iraq, Afghanistan, and more, ABC News reports.
The photography blog, "In Focus," on The Atlantic's website posted photos of Hondros' taken while he covered the war there.
