Hetherington, a Briton, was killed inside the rebel-held city, with three other journalists injured, said the reports.

He was working there as a photographer for the American magazine Vanity Fair.

Hetherington, 41, co-directed the documentary film "Restrepo" which was nominated for the 2011 Academy Award for Best Documentary. The movie tells the story of a group of U.S. soldiers stationed at an outpost in northeast Afghanistan.

He also won the World Press Photo of the Year award for his coverages on U.S. soldiers in Afghanistan.

Hetherington was born in Liverpool and studied at Oxford University.
