A 30-year-old female member of a flute band has died after being hit by a Range Rover at an Orange parade.
The vehicle, which was part of the parade, crashed into Cahard Flute Band as it left the demonstration field at Killyleagh, County Down, on Monday.
Debbie Jordan, from Saintfield, was airlifted to Musgrave Park Hospital and later transferred to the Royal Victoria Hospital, but died from her injuries.
A boy, nine, who suffered a leg injury in the accident was taken to hospital.
A police investigation is to be carried into the circumstances surrounding Ms Jordan's death.
Rev Mervyn Gibson, who conducted the service at the County Down demonstration, said: "The main demonstration was over and the districts were leaving the field.
"I would say half the districts had left the field when the parade was stopped and it soon became apparent there had been an accident.
"One of the official cars had crashed into a band and basically that's as much as people know, and we know sadly the outcome."
The clergyman continued: "The bands world is a small community in many ways, particularly in the rural areas, and this band would have taken part in competitions, so I imagine the lady concerned would have been well known to many people.
"I know the grand master and the county master will be calling with the families involved in this terrible tragedy, and certainly the whole institution, the whole bands world, will be praying for her family at this time.
Rev Gibson said a review of the involvement of cars in parades was "for for another day, but certainly there are lessons to be learnt as nobody wants this to happen again".
William Dick, chairman of Down District Council, and a member of the lodge the band was attached to, said the "freak accident" had left the local community in shock.
"She (Ms Jordan) was from a very respected family within the community and there is a terrible sense of shock," said the DUP councillor.
