Vagabov's successor is Israpil Velidjanov (Emir Khasan), whom then-Daghestan Interior Minister Lieutenant General Adilgirey Magomedtagirov identified in March last year as one of the republic's four most experienced militant leaders.
Velidjanov was named emir of the Derbent jamaat in southern Daghestan in October 2008. That fighting unit came to prominence only during the early months of that year. In July 2009, they launched a high-profile attack on the Derbent city police headquarters, killing two police officers and injuring four more.
To judge from a video clip of Velidjanov and his fighters posted in the spring of this year, he is in his early 40s and definitely a soldier's soldier. Vagabov, by contrast, clearly sought to promote an image of himself not just as a military commander, but also as a legal and theological authority, and thus as the logical successor to Umarov -- or even as the Imam Shamil of the 21st century.
