A Chechen terror organization which boasts “as many as 15,000” fighters has pledged its loyalty to Islamic State of Iraq and Levant (ISIL).

The Caucuses Emirate is responsible for over 900 attacks in Russia since 2007 and includes extremists from Chechnya, Daghestan and Ingushetia.

“We need to hurry up and unite so we can cut off the heads of the infidels,” the group’s leader, Aslan Byutukayev, said in a new propaganda video.

Professor Gordon Hahn of the Monterey Terrorism Research and Education Program said the Caucuses Emirate could furnish ISIL with thousands of new fighters.

“The entire CE [Caucuses Emirate] insurgency and terrorist movement may be estimated to number some 15,200 soldiers, leaders and facilitators,” Hahn wrote in his book The Caucasus Emirate Mujahedin.

After a series of deadly attacks between 2009 and 2014, Caucuses Emirate was recognized as a terrorist organization by the UK, United States, Russia and the United Nations.

CE was responsible for the 2009 detonation of a bomb on the Nevsky Express high speed train that left 27 people dead and over 50 wounded. The jihadist group also claimed responsibility for two suicide bomb attacks on trams in the Russian city of Volgograd which killed 34 in December 2013.

According to Kurdish commanders, ISIL is currently said to have as many as 200,000 fighters and as many as eight million people living under its reign across the Middle East and North Africa.

ISIL may add several thousand more fighters if a recently released video entitled “Soon, Soon” proves to be true. In the video, an unknown organization called “ISIL Tunisia Province” said it planned to set up a base and supply ISIL with 3,000 jihadi soldiers.
