Boko Haram was founded in 2002 to seek the establishment of an
Islamic state and fight against the
Westernization of Nigeria, which the group says is the root cause of
criminal behaviour in that country. From 2009 to 2013, violence linked to the
Boko Haram insurgency resulted in 3,600 deaths, the victims including 1,600 civilians. In mid-May 2013, Nigeria declared a
state of emergency in
Adamawa,
Borno, and
Yobe States aiming to end the
Boko Haram insurgency. The resulting crackdown has led to the capture or killing of hundreds of
Boko Haram members, with the remainder retreating to mountainous areas from which they increasingly targeted civilians. Since 2010,
Boko Haram has targeted schools, killing hundreds of students. A spokesperson said such attacks would continue as long as government soldiers continued to interfere with traditional
Koran-based education. More than 10,000 children are no longer able to attend school due to
attacks by Boko Haram. Roughly 20,000 people fled Yobe State to
Cameroon during June 2013 to escape the violence. In June 2013,
Nigerian soldiers beat students at a Koran-based school, angering Boko Haram members. An attack on 16 June by Boko Haram
militants killed seven children, two teachers, two soldiers, and two militants. The next day, militants killed nine students who were taking exams. On 4 July, gunmen attacked and killed a school headmaster and his family. Mamudo is from
Potiskum, Yobe State's largest city. Boko Haram have carried out several major attacks there. ==Attack==
