Earthrace Conservation calls for an immediate halt before thousands more seal pups are brutally killed.

Graphic footage was captured by covert filming of the annual seal cull on one of Namibia’s highest security beaches, Atlas Bay, a lucrative diamond mining area.

The footage, released July 2013, shows dozens of seal pups being driven across the beach to be clubbed to death by a team wielding what appear to be pick axe handles before their carcasses are loaded into a pick-up truck for disposal.
