Family of photographer urge Libya to investigate his death

Relatives of Anton Hammerl, who was killed in 2011, hope new government will help locate his body

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.
