Original post: Veteran war photographer Tim Hetherington, who co-directed the award-winning film Restrepo, was killed today in the besieged Libyan town of Misrata, CNN reports.

Three colleagues were also injured, including Chris Hondros, a photographer for Getty Images, and 2005 winner of the Robert Capa Gold Medal for "best published photographic reporting from abroad requiring exceptional courage and enterprise."

In his last tweet from embattled Eastern Libya on Tuesday, Hetherington, a contributing photographer for Vanity Fair magazine, writes: "In besieged Libyan city of Misrata. Indiscriminate shelling by Qaddafi forces. No sign of NATO."

The Washington Post reports that Post reporter Leila Fadel was at the hospital in Misrata working on a separate story when Hetherington and Hondros were brought in. She said Hondros had apparently been hit by shrapnel and had suffered a "severe head injury."

Earlier posting: veteran war photographer was reported killed and three colleagues injured today in the besieged Libyan town of Misrata, The New York Times reports.

Several news sites and Twitter postings, including The Times have identified the photographers, but because much of the information is conflicting we are withholding the names for the moment.

The Times quotes an unidentified colleagues at a triage center in Misrata as saying the wounds to two of the photographers are "grave" and that one of them is "clinging to life."

The Times says early reports indicated the photographers were working together near the front lines when they were hit by a rocket-propelled grenade.

Hetherington, a contributing photographer for Vanity Fair magazine, was co-director, with Sebastian Junger, of the documentary about a platoon of Soldiers in Afghanistan. Restreopo won a Grand Jury Prize at the 2010 Sundance Film Festival.

Hetherington, a native of Liverpool, tweeted regularly from the front lines. In his last last tweet, Hetherington wrote:
