Photographers Chris Hondros and Tim Hetherington were killed in an explosion two years ago, while traveling with rebel fighters in Libya. To this day, it isn't clear whether it was a mortar or a rocket propelled grenade that took their lives. Such is the confusion of a war zone.

Hetherington spent his life demystifying conflicts — recording their brutal realities in black and white. From the sprawling conflicts in West Africa to the mountains of Afghanistan, Hetherington spent much of his life in places where existence can be violent, terrifying, and short.

In 2007 and 2008 Hetherington and Junger lived with a company of U.S. soldiers in Afghanistna's Korangal Valley for the documentary "Restrepo." Junger has a new documentary on the life and work of Hetherington.

L.A. Times "Sebastian Junger's heartfelt, intense and maddening (in the right way) documentary "Which Way Is the Front Line From Here?: The Life and Time of Tim Hetherington" examines the open-hearted, peripatetic nature of his acclaimed "Restrepo"co-director, who was killed in a mortar attack in 2011 covering the civil war in Libya."
