Celebrated photographer Tim Hetherington was killed in the Libyan city of Misrata after he and other photographers working near the front lines were struck by a rocket-propelled grenade. Among other accomplishments, Hetherington was a co-director and producer of the film Restrepo. Photographers Chris Hondros and Guy Martin were also severely injured in the attack. Hondros is reportedly still in a coma after being revived, while Martin suffered shrapnel wounds and was undergoing vascular surgery. For several weeks, Misrata has been the scene of intense fighting between troops loyal to Moammar Gadhafi and the rebel fighters trying to overthrow his regime.
