Oscar-nominated director Tim Hetherington died Wednesday in the midst of heavy fighting in Libya, The Washington Post reports.

Hetherington, 40, was in the war-torn country with Pulitzer Prize-nominated American photojournalist Chris Hondros, 41, and were killed when fighting broke out between Moammar Gaddafi's forces and rebels in the city of Misrata. Two other photojournalists were also hurt during the attack.

British-born Hetherington rose to fame when 'Restrepo,' his documentary chronicling the deployment of U.S. soldiers in Afghanistan, was nominated for an Academy Award earlier this year. He was most recently based in Brooklyn, New York.

On Tuesday the director took to Twitter to update his followers on the situation in Libya. "In besieged Libyan city of Misrata," he wrote. "Indiscriminate shelling by Qaddafi forces. No sign of NATO."
