A mother and two of her children have been killed in a devastating car crash outside an Australian hospital. The 20-month old boy, eight-year-old girl and the 35-year-old woman were killed when their car hit a curb and crashed into a power pole outside the Royal Children's Hospital in Melbourne.

Victoria police said in a statement on Friday that the "exact cause of the crash is yet to be determined" but that they have ruled out terrorism.
