Video - Suicide bombers kills 19 in Nigeria

Four suicide bombers have targeted a civilian self-defence force in Nigeria, killing 19 people. The bombers are reportedly from the militant group, Boko Haram. This has been the deadliest attack in months in the northeastern city of Maiduguri - the birthplace of Boko Haram's eight-year insurgency. Borno state police commissioner Damian Chukwu said 23 others were wounded during the attacks. Reports also state that at at least one of the suicide bombers was female. Boko Haram has increasingly used girls and young women to carry out attacks on marketplaces, checkpoints and other targets.
