Probably Not Enough to Qualify As a Mass Murder

But not for lack of trying.  8/13/19 U.K. Daily Mail:

Blood-soaked man 'shouting Allahu Akbar' in Sydney's CBD attempts to stab multiple people - with one woman rushed to hospital and another found dead with her throat slit in a nearby building

But no gun, so move along, there's nothing here to see.

Police are investigating whether the alleged attacker, Mert Ney, 21, from Blacktown in the city's west, had escaped from a mental institution.

That seems likely in spite of  Allahu Akbar.
