Police in Belfast have begun a murder investigation after a baby died in the Ardoyne area last night.
A woman was arrested following the incident involving two young children in Brompton Park.
Detective Chief Inspector Chris Millar said: "Police were called to the house shortly after 8pm and discovered the injured baby and another injured child in the house.
"Despite the efforts of the emergency services the baby was sadly pronounced dead at the scene. The other young child was taken to hospital and remains in intensive care.
"A 29-year-old woman who was also in the house has been arrested on suspicion of murder and attempted murder and remains in custody at this time.
"Our thoughts are with the baby's family, who are being supported by Family Liaison Officers.
"While our investigation is at any early stage I can confirm that at this stage, we are not looking for anyone else in relation to this tragic death."
Police have not confirmed the ages of the children involved.

A post-mortem examination on the body of the baby will be carried out tomorrow.
A Catholic priest said that the community of Ardoyne is "shocked" and "reeling" following the tragic incident.
Fr Gary Donegan, who was formerly based in Ardoyne and is now based in north Belfast said the close-knit community is going through an "unparalleled kind of pain" despite all the suffering it has seen down through the years.
Speaking on RTÉ's News at One, he said that the nature of the tragedy and the fact that children were involved means "to say they are in shock is an understatement".
Fr Donegan said the community is strong and proud, but there is a numbness today and for those who witnessed last night's "very distressing scenes", many were left traumatised.
He said he visited the scene this morning to carry out a blessing, saying the family involved are well-known locally.
Sinn Féin MP for North Belfast John Finucane said the Ardoyne community is "in shock".
Speaking on RTÉ's Morning Ireland, Mr Finucane it was very traumatic for some neighbours that were "quite literally watching what was unfolding emerging from the house" and for the first responders who came to the scene.
SDLP deputy leader and North Belfast MLA Nichola Mallon said: "It is important that the PSNI are given the space and full cooperation to fully investigate this terrible incident."
