Last modified on Thu 1 Apr 2021 09.21 EDT The family of a British-based photographer killed in 2011 by pro-Gaddafi forces during the Arab spring have launched a campaign to pressure Libya to investigate his death. Anton Hammerl, 41, was shot after being targeted as part of a small group of journalists, including the US reporter James Foley who himself was subsequently kidnapped and murdered by Islamic State in Syria. Left for dead in the desert after Foley and fellow journalists Clare Morgana Gillis and Manu Brabo were captured, Hammerl’s body has never been recovered. The case was briefly investigated as a war crime by the international criminal court, but it was dropped after the death of Muammar Gaddafi and the fall of his regime.
