The mother of three children found dead in their home has been charged with their murders
Theresa Riggi, 46, was arrested and charged over the deaths of her eight-year-old twins Augustino and Gianluca Riggi and their five-year-old sister Cecilia.
Their bodies were found in their home in Edinburgh following reports of an explosion on Wednesday.
A Lothian and Borders Police spokesman said: "A 46-year-old woman has been arrested and charged with murder in connection with the petition warrant which was granted earlier today. Due to the medical condition of the accused, it is not at this time known when she will appear in court."
It was initially thought the children had died in a gas explosion, but police later said there was no fault with the supply.
Mrs Riggi was found injured on the ground outside the house, after apparently falling from the second floor. She is still in a "serious but stable" condition in Edinburgh's Royal Infirmary hospital, police said.
Earlier, Edinburgh Sheriff Court issued a petition warrant for her arrest after post-mortem examinations were carried out on the bodies of the children.
The children's father Pasquale Riggi said the deaths of his three "beautiful" children was an "immense and tragic loss".
He was traced to an address in Aberdeen following the deaths and said: "Thanks to all who have offered such great comfort and support. We request that the media respect our privacy at this difficult time."
The family came from California and Colorado and Mr Riggi has worked for Shell since 1987. He has been in Aberdeen for a number of years and in the country for 13 years.
