WA woman charged with stabbing murder

A woman has been charged with murder over the stabbing death of a younger woman in a shopping centre car park in Western Australia's Kimberley region.

Police were called to the Kununurra car park on Monday night after receiving reports a woman was armed with a knife and acting in a threatening way.

They say they later saw the woman move towards the 29-year-old victim with the knife.

She died at the scene with serious stab wounds to her chest and the second woman was arrested.

Police say the other woman, 37, has been charged with murder and is due to appear in the Kununurra Magistrates Court later on Wednesday.
