Documentarian and Oscar-nominated director Tim Hetherington was killed in Libya on Wednesday, The New York Times reports. Three photographers, Chris Hondros, Guy Martin and Michael Christopher Brown were also injured in the attack.
The men were on location documenting the conflict between Muammar Gaddafi's forces and Libyan rebels when they were struck by a rocket-propelled grenade.
Hetherington is best known for directing the 2010 Oscar-nominated film Restrepo. The documentary follows him and fellow journalist Sebastian Junger as they spent a year in Afghanistan on assignment for Vanity Fair. Hetherington also produced many pieces for ABC News' Nightline.
"Tim was one of the bravest photographers and filmmakers I have ever met," ABC News' James Goldston told The Hollywood Reporter.
Hondros is said to be in critical condition, while Martin is undergoing surgery and Brown is recovering.
