Dokka Umarov
In February 2008, he was reportedly killed by officers of the Russian Ministry of Internal Affairs (MVD) during a search operation near the village of Arshty in Ingushetia. Interfax, however, refuted Muhannad's death the same day, saying it was a different militant. Dokka Umarov later appeared on video with Muhannad to refute statements of his death, calling them lies and propaganda.
