Authorities have confirmed that they are investigating the alleged throwing of a bomb into an invasion day rally crowd in Perth as a 'potential terrorist act.' WA police allege a 31-year-old man threw a device containing screws and ball bearings surrounded by an explosive liquid into the crowd of about two-and-a-half-thousand in the heart of Perth’s CBD. First Nations responses express concern and have questioned why the government has not used stronger language to condemn the attack.
