REPUBLIKA.CO.ID, SYDNEY -- An Australian woman was arrested in the killings of eight children, seven of whom are believed to be her own, police said Saturday. The children were found dead inside the woman's home.

The 37-year-old woman, who is recovering in a hospital from stab wounds, was under guard and speaking with police, Queensland Police Detective Inspector Bruno Asnicar said. She has not yet been charged.

Police haven't said how the children died. But Asnicar said they're examining several knives in the home that may have been the weapon used to kill them. The children were identified as four girls and four boys, ranging in ages from 2 to 14 years old, Asnicar said. The woman is thought to be the mother of seven of the children. The eighth is believed to be her niece.

Queensland police were called to the home in the Cairns suburb of Manoora on Friday morning after receiving a report of a woman with serious injuries. When they got to the house, they found the bodies of the children.
