BREAKING. Lone Wolf Knife Attack Kills 1, Wounds 3 in Germany but We May Never Know the Motive

Sadly, I did not write the headline sarcastically:

A machete-wielding man has killed one and injured several others after going on the rampage through a German supermarket this afternoon.

The attacker, who reportedly screamed Allahu Akbar, ran into an Edeka shop in the northern city of Hamburg and knifed a customer to death before slashing at four others as he fled.

He ran off but was pursued by passers-by who wrestled him to the ground and called police who made an arrest.

Heavily armed officers have locked the area down and police helicopters have been seen above the crime scene. A motive for the knifing has not yet been established.

Great photos and the lone wolf claim can be found here.
