Muhammad ibn Abd al-Karim al-Khattabi (Arabic: محمد بن عبد الكريم الخطابي‎), better known as Abd el-Krim (1882/1883, Ajdir, Morocco – 6 February 1963, Cairo, Egypt) was a Moroccan political and military leader. He and his brother M'Hammad led a large-scale revolt by a coalition of Riffian tribes against French and Spanish colonization of the Rif, in Morocco. His guerrilla tactics, which included the first-ever use of tunneling as a technique of modern warfare, directly influenced Ho Chi Minh, Mao Zedong and Che Guevara.
