Three suicide bombers killed four people and injured eight others in a village near the northeast Nigerian city of Maiduguri. Maiduguri police spokesman Victor Isuku said a man and two women blew themselves up when they were challenged by a member of the Civilian JTF, a government-approved militia group, just outside Maiduguri, the city worst hit by jihadist group Boko Haram's eight-year insurgency.<br/><br/>The blasts, in the village of Umariri around 7 kilometres from the city, occurred on Saturday around 9 pm local time. He said, four people which include a Civilian JTF, a woman and her two children died while eight others sustained injuries.<br/><br/>It is the latest in a string of attacks in the last few days to bear the hallmarks of Boko Haram, which has killed around 15,000 people and forced more than 2 million people to flee their homes in Africa's most populous nation since 2009.<br/><br/>A man claiming to be the group's leader appeared in a video circulated on Friday in which he claimed responsibility for bombings in Maiduguri and a raid on the nearby town of Magumeri last week.
