Born in 1986 in Stuttgart into a partially German Muslim family, Yamin Abou-Zand grew up in Baden-Württemberg until moving with his parents to Königswinter in 2000. There, he married a German Muslim and rented his own apartment. The couple had no children and lived secluded, though neighbors said that they were generally nice people. Yamin also began working at the Deutsche Telekom in the department for Recruiting and Talent-Acquisition, where he was initially considered to be a "promising, committed and very courteous employee". In late-2013, his co-workers noticed that he became increasingly extremist in his religious views. Eventually, he began to openly express sympathy for ISIL, whereupon the Telekom reported him to the German security agencies. Yamin eventually quit his job in late-2014. In early-2015, he and his wife disappeared without informing their families, who reported them missing to local authorities. The two appear to have travelled to Turkey, and from there to Syria in order to join ISIL. Soon after, Yamin adopted his nom de guerre "Abu Umar al-Almani" and joined Millatu Ibrahim, a German Salafist organization led by the Austrian Mohamed Mahmoud that had become a unit of ISIL's military. He gained prominence in August 2015 by appearing in the first ISIL propaganda video in German together with Mohamed Mahmoud. In the video, shot in Palmyra, the two tried to encourage German Muslims to travel to Syria and join ISIL. Abu Umar claimed that "the jihad is like vacation for us. We are here at one of the most beautiful places in Syria." In the case German jihadists could not travel to Syria, he ordered them instead to commit terrorist attacks in Germany and Austria, saying that they should "attack the kuffar, in their own homes! Kill them where you find them!" The two ISIL fighters justified this as revenge for the German support of the anti-ISIL coalition, and the Bundeswehr mission in Afghanistan. Abu Umar then proceeded to execute a capturedSyrian Army soldier. Since his appearance in the propaganda video, Abu Umar was wanted by the German security services for murder and war crimes. German Salafists, including those with sympathies for ISIL and al-Qaeda, widely condemned the execution and the video, with prominent Islamist Bernhard Falk calling Abu Umar a psychopath. In course of the following year, Abu Umar became an emir and one of the leading ISIL commanders in the Al-Thawrah District, where he helped to organize the defenses against the SDF-led Raqqa offensive. On 25 March 2017, he was killed with three of his bodyguards by YPJ fighters during clashes near Tabqa Dam.
