A fire that broke out at a school for the blind Princess Anne was meant to visit during her trip to Uganda later this week has killed 11 children. Police are investigating the causes of the deadly fire at Salama School for the Blind in Mukono, east of Uganda’s capital city Kampala, which claimed the lives of children aged between seven and 10.The youngsters were in their dormitories when the fire broke out in the early hours of Tuesday.The pupils, according to Mukono district security head and presidential representative Fatuma Ndibasa, were burnt “beyond recognition” and they would need DNA tests to establish the children’s identities.Richard Muhimba, a trader who lost his son in the fire, told the AFP news agency: “No words can explain the pain I am going through.”The incident also injured seven more children, treated for severe burns, while three others managed to escape.
