Tim Hetherington, who was nominated for an Oscar for co-directing the documentary Restrepo earlier this year, has been killed covering the fighting in Libya. Chris Hendros, a Pulitzer Prize-nominated photojournalist, was also killed and two other prominent photographers were wounded. Heatherington and Hendros were covering the fighting in the city of Misrata, a rebel stronghold that has been ruthlessly bombarded by forces loyal to strongman Colonel Khadafy. In his last Tweet, Hetherington had reported that the city was being bombed indiscriminately and that there were no signs of NATO forces to help repel the attacks on the civilian population. Hetherington and Hendros were mortally wounded shortly thereafter. Hetherington's film Restrepo is a blistering look at a U.S. military platoon sent to guard a remote mountain outpost in Afghanistan. Named after a platoon medic who was killed in action, the Restrepo outpost is under constant siege from the Taliban. Hetherington and his co-director (and best-selling author) Sebastian Junger, won acclaim for their courageous filming of the platoon under fire and for personalizing the characteristics of each of the young soldiers.The film does not take a political position on the nature of the conflict, but regardless of where you stand on the U.S. presence in Afghanistan, it's easy to see the futility of sending under-armed and outnumbered platoons to defend remote outposts of dubious strategic value. The U.S. military has since concurred and announced a change in strategy, saying it will be abandoning these missions in favor of concentrating forces in more populated areas. Hetherington and Hendros are the third and fourth journalists known to have been killed since the fighting in Libya began. Despite air raids launched by the U.S., France and the UK, the Libyan rebels have thus far not been able to use the Allied support to drive Khadafy from power, though he has undeniably been weakened.
