Police in Western Australia have shot dead a man after several people were stabbed at a shopping centre in the Pilbara region.

Five people were injured in the attack at the South Hedland Square centre – two of them are in a serious condition.

Witnesses told local media they saw a man waving “a great big knife” at shoppers and police officers, before hearing screaming and bangs.

WA Premier Mark McGowan called it “a tragic and awful set of events”. “He has been tasered by police, that didn’t stop him. He lunged at police officers and then he was shot by police officers,” the Australian Broadcasting Corporation quoted Mr McGowan as saying.

Police said there was no ongoing threat to public safety and are appealing for people to come forward with any video evidence. There has been no suggestion the incident was terror-related.
