"UK Jihadist was British-born man". 

The left and their globalist immigration policies are responsible for this. Their media outlets (be it "independent" or state owned) mask the truth because saying it was another Muslim terrorist contradicts their position that islam is a religion of peace, and immigration is a good thing. 

Have a look at the radicalization of Birmingham (where this attacker and many of the other 8 detained are from). Everything from Sharia marches proclaiming Christianity and Western values to be dead, to self anointed "Sharia Police" patrolling for anything that offends them. Start reporting the truth. Pathetic.
