A 20-year-old woman from Iraq whose father allegedly hit her with his car because she had become too Westernised has died from her injuries, authorities said.

Noor Faleh Almaleki had been in hospital since October 20, when police say her father ran her and her boyfriend's mother down with his Jeep as the women were walking across a parking lot in the west Phoenix suburb of Peoria.

Peoria police spokesman Mike Tellef said Noor died on Monday. The other woman, Amal Khalaf, is expected to survive.

Family members say Faleh Hassan Almaleki attacked his daughter because he believed she had become too Westernised and was not living according to his traditional Iraqi values.
