A man and woman have been charged with murder after two boys died following an "incident" at a house in Sheffield.
Two boys, aged 13 and 14, died, and four children were "rescued" from the property in Shiregreen on Friday morning.
The woman also faces three counts of attempted murder following the incident.
The pair are due to appear in court on Monday.
The four other children needed hospital treatment after the incident.
South Yorkshire Police previously said a 37-year-old man and a 34-year-old woman had been arrested on suspicion of murder.
On Sunday, the force said: "A man and woman arrested on Friday 24 May at an address in Shiregreen have now each been charged with murder x 2.
"The woman has also been charged with attempted murder x 3.
"Both will appear at Sheffield Magistrates' Court tomorrow.
"The two cannot be named for legal reasons."
The force said on Saturday that four other children who were "rescued" from the house had been released from hospital.
They are aged 11, 10, three, and seven months and cannot be named for legal reasons.
Officers were called to the semi-detached house in Gregg House Road at around 7.30am on Friday.
Detectives have given no indication about the nature of the incident, but have confirmed it was not a shooting, and said it was confined to the one property.
A spokesman said detectives were not looking for anyone else in connection with the incident.
People living nearby saw more than a dozen police cars and four ambulances arrive on the tree-lined road and an air ambulance land in the grounds of Hartley Brook Primary Academy, just 100 metres from the scene.
