Dambe warriors fight in the ring, the ancient brutal martial art of Dambe associated with Hausa people of West Africa during a weekend match in Dei-Dei, Abuja, Nigeria on June 30, 2019. Matches last three rounds, which have no time limits. A round ends when there is no activity, a participant or official halts the round, or a fighter's hand, knee or body touches the ground.
