From The WSJ:
The Oscar-nominated co-director of the 2010 film "Restrepo" was killed Wednesday in Libya amid a battle between rebel and government forces.
Tim Hetherington, who was also a contributing photographer to Vanity Fair, was killed when an explosive round landed in a group of press photographers accompanying a rebel patrol in the western city of Misrata.
Another photographer, Chris Hondros, sustained a grave head wound in the incident and was not expected to survive. At least one other photographer, Guy Martin, was also injured and undergoing surgery.
