TWO young children were stabbed to death in Bradford today.

Police were called to an address in Mint Street, Undercliffe, at 11.28am after they were contacted by paramedics attending a report of an injured child.

Officers found the two girls, aged one and three, with stab wounds.

Both children received treatment at the scene but were pronounced dead a short time later, said a West Yorkshire Police spokesman.

A 24-year-old woman has been arrested on suspicion of murder as the investigation continues.

Police are not currently looking for anyone else in connection with the incident, said the police spokesman.

Tonight, a dozen bunches of flowers had been left at the scene, including pink roses.

A message attached to one bunch of flowers read: "RIP little angels - gone far too soon."

Another said: "You are in safe hands in heaven now with the angels."

A group of women and children, who live on the road nearby, lay bunches of flowers at the scene and wiped tears from their eyes as they walked away.

Kathleen Muller, 67, said: "We've got kids ourselves and we only live on that street. It's awful. We've left the flowers for the kiddies. She must have been in a state."

Ms Muller's daughter, Joanne Shoesmith, 45, said the area was usually quiet.

Many neighbours said they would be afraid to let their children play out in the street following the stabbings.

Joanne Cannar, 27, who has two children aged three and seven, said: "I'll probably be more wary now. It's so close to home. Everyone on the street keeps themselves to themselves. It's normally quiet, it's normally a nice area."

Ms Cannar said she did not know the woman or children involved but had sometimes heard noise from the building where the stabbings took place.

"Kids scream from the windows but you just think it's kids having tantrums and things like that," she said.

"I was picking my youngest up from nursery this morning and I've seen an ambulance and an ambulance car but I didn't know why."

John Adeleye, who also lives on the street, said: "The police arrived and paramedics and ambulance came. They tried to save the kids but eventually they passed away."

He added: "This environment is usually a very peaceful place. We saw children from the building playing around and having fun. We're very shocked."

At about 1pm, a police van, police car, and two unmarked vehicles could be seen parked at the end of the street. 

A paramedic fast response vehicle could be seen parked near the property where the children were stabbed. 

Shortly before 1.30pm, three minibuses arrived at the scene and blocked off access to the car park, although no-one appeared to have been transferred to the vehicles at that point.

A second emergency ambulance vehicle arrived at the scene at 1.40pm. Both vehicles left a few minutes later.

Michael Jameson, strategic director of children's services at Bradford Council, said this afternoon: "This is a very tragic and shocking incident.

"Our thoughts are with the family of the children, who only arrived in Bradford very recently from a neighbouring area.

"We are doing all we can to assist the police with their inquiries and support those affected."

News of the tragedy was also greeted with shock by councillors in the Bowling and Barkerend ward where the tragedy happened.

Councillor Imran Khan (Lab) said details of the deaths were sketchy so far but it was "a very sad and very unfortunate incident".

He added: "It's too early to know exactly what's happened. I can't get my head round it.

"I'm lost for words that something as dreadful as this has happened here and these two children have lost their lives."

And Councillor Hassan Khan (Lab) said: "My sorrow and sympathy goes out to everyone involved."

One resident of neighbouring Hatfield Street, said: "I've lived here for years and I've never seen anything like this.

"I don't think people can believe what has happened. It's very, very sad."

Another, who lives in nearby Lowther Street, said: "I heard the news that it was in Undercliffe so I came back and saw all the commotion.

"It's normally a really quiet street. Anything to do with kids is terrible, you just don't know the circumstances of what has happened."
