Two children have died after being stabbed in the English city of Bradford.

A 24-year-old woman has been arrested on suspicion of murder.

Police were called to an address in Undercliffe just before lunchtime on Tuesday, after being contacted by paramedics attending a report of an injured child.

Officers discovered two young children with stab wounds. Both were given treatment at the scene but died shortly afterwards.

Police are not looking for anyone else in connection with the killings, and enquiries are continuing.
