Award-Winning War Photographer Killed in Libya VOA News April 20, 2011 Tim Hetherington (file photo) Photo: AP Tim Hetherington (file photo) An Oscar-nominated film director and war photographer was killed Wednesday in the besieged Libyan city of Misrata, and three Western colleagues were wounded while covering battles between rebels and government forces. British-born Tim Hetherington was killed by a round of mortar fire on Tripoli Street, the main thoroughfare and focus of the fighting in Misrata, the only rebel-held city in western Libya. The city has come under weeks of relentless shelling by forces loyal to leader Moammar Gadhafi. News reports say two photographers - Chris Hondros and Guy Martin - were gravely wounded in the blast. Their prospects for survival are unclear. A third photographer, Michael Brown, suffered light injuries. Hondros, an American working for Getty Images, suffered a severe brain injury and is in critical condition on a respirator. Martin, a British citizen who works for the Panos photo agency, underwent surgery for shrapnel wounds. The acclaimed 41-year-old Hetherington co-directed the 2010 documentary Restrepo, about U.S. soldiers on an outpost in Afghanistan. Hondros, also 41, has covered conflict zones since the late 1990s, including Kosovo, Angola, Iraq and Afghanistan. His awards include the Robert Capa Gold Medal, one of the highest prizes in war photography. His work in Liberia earned him a Pulitzer Prize nomination. The New York-based Committee to Protect Journalists says two other journalists have been killed in the Libyan conflict. An unknown gunman killed Mohammed al-Nabbous, founder of the online Libya Al-Hurra TV, as he was streaming live audio from a battle in Benghazi on March 19. Cameraman Ali Hassan al-Jaber was shot when his al-Jazeera television crew was ambushed near Benghazi earlier in March. CPJ says three international media workers and at least six Libyan journalists are missing and suspected to be held by pro-Gadhafi forces.
