A Chechen commander known as Saifullah al Shishani is reported to have been killed during fighting in the Syrian city of Aleppo. Units from the Al Nusrah Front for the People of the Levant, al Qaeda’s official branch in Syria, and Ahrar al Sham, one of the larger units in the Islamic Front, are currently fighting Syrian forces in an effort to take control of a prison in Aleppo. The two jihadist groups teamed up in December in an effort to take the prison and an adjoining hospital.

Saifullah led the “Al-Khilafa army,” or Army of the Caliphate, according to the Syrian Observatory for Human Rights. It is likely that this is a reference to the Ansar al Khilafah, of Supporters of the Caliphate, an Al Nusrah Front unit that was formed in December 2012. [See LWJ report, Syrian jihadists form ‘Supporters of the Khilafah’ Brigade]. The Al Nusrah Front and Ansar al Khilafah seized a village near Aleppo in July 2013 and executed Syrian soldiers.

Saifullah was previously a commander in the Muhajireen Army, which is led by Chechen commander Abu Omar al Shishani (the Chechen) and who has sworn allegiance to the Islamic State of Iraq and the Sham. Last year, Saifullah and another Chechen commander split with Abu Omar and the ISIS.
