Syrian Civil War Yamin Abou-Zand[2] (1986 – 25 March 2017), better known by his nom de guerre Abu Umar al-Almani (Arabic: أبو عمر الألماني; Abū ʿUmar al-Almānī), was a prominent German commander of the Islamic State.

[7] Yamin also began working at the Deutsche Telekom in the department for Recruiting and Talent-Acquisition,[8] where he was initially considered to be a "promising, committed and very courteous employee".

[7] Soon after, Yamin adopted his nom de guerre "Abu Umar al-Almani" and joined Millatu Ibrahim,[3] a German Salafist organization led by the Austrian Mohamed Mahmoud that had become a unit of the Islamic State's military.

[3] German Salafists, including those with sympathies for IS and al-Qaeda, widely condemned the execution and the video, with prominent Islamist Bernhard Falk (de) calling Abu Umar a psychopath.

[8] In course of the following year, Abu Umar became an emir and one of the leading IS commanders in the Al-Thawrah District, where he helped to organize the defenses against the SDF-led Raqqa offensive.
