This group is a renegade militant group called Takfiri who are quick to declare war on Muslims if they disagree with them, they think that every muslims states are kafir states because they are not following the principles of shariah and its justified to first declare Jihad on the muslim states. They are ideologically anarchists and outcastes even in other Jihadi groups.
This is very dangerous and the Saudi grand mufti has also warned the muslims of such elements waging fake Jihad.
