Australian police have shot and killed a man who wounded several people in a shopping mall in the Pilbara area, BBC News reported on Friday.

About five people were injured by the man and two were seriously injured, the source said. Eyewitnesses said the man waved a large knife in front of shoppers and police before he heard screams and gunshots.

There have been no confirmed reports so far of the cause, nor is it a confirmed terrorist act.
