Australian authorities have charged a woman in the northern city of Cairns with the murder of seven of her children and her niece.
Mersane Warria, 37, was charged while in hospital where she is being treated under guard for self-inflicted knife wounds, police say.
Post-mortem examinations are being carried out to determine the exact cause of the eight victims’ deaths.
The four boys and four girls were aged between 18 months and 14 years.
Police found a number of weapons at the scene, including knives, which are being examined.
Officers said they were looking at various possibilities for the deaths, including suffocation.
