Worshippers of the iron god Ogun gather during an annual prayer and sacrifice ceremony in Abuja, Nigeria June 23, 2015. Every year worshippers offer a sacrifice to Ogun, a traditional Nigerian deity, in hope of an auspicious year ahead. Taxi drivers, blacksmiths, panel beaters and mechanics - trades that depend on metal for their livelihood - pay homage to Ogun, led by high priest Gbenga Saala. As part of the ceremony, the priest pours the dog’s blood on symbols of these workers’ trade: keys, spanners and other tools piled up in a metal barrel.
