A child has been killed and their sibling is fighting for their life after their father stabbed them in their beds and threw them from a 50ft balcony in Sweden, local reports say.
Stockholm police have launched a murder and attempted murder probe after both parents were arrested.
The identity of the two suspects has not been confirmed by police who have only said the pair had a relationship with the children and each other but Swedish media said it is understood to be the children's mother and father.
The father, 45, is believed to have stabbed himself after carrying out the horrific attack.
The children, who are both under the age of 10, were rushed to a hospital in a helicopter.
But the younger of the two siblings did not survive the night while the other child has life-threatening injuries, police said.
A passerby found the children lying on the ground outside the block of flats and alerted police at around 9.45pm yesterday.
