better known by its Hausa name Boko Haram (pronounced [bōːkòː hàrâm], "Western education is sinful")[4] — is an Islamic jihadist militant organization based in the northeast of Nigeria,[5] north Cameroon and Niger.[6][7][8][9] Founded by Mohammed Yusuf in 2001,[10] the organisation seeks to establish a "pure" Islamic state ruled by sharia law,[11] putting a stop to what it deems "Westernization."[12][13] The group is known for attacking Christians and government targets,[12] bombing churches, attacking schools and police stations,[14][15] but has also assassinated members of the Islamic establishment.[16] Violence linked to the Boko Haram insurgency has resulted in an estimated 10,000 deaths between 2001 and 2013 and roughly 3,600 killed, including 1,600 civilians between 2009 and 2013.[17][18][19][20][21]
