The four of them, aged six, eight, ten and eleven, are all now proclaimed dead - two from the same family.
It really is a tragedy as none of them were likely to be aware of the danger. There have not been enough days with sub zero temperatures for the ice to have been stable enough even to support a young child let alone four of them.
I really do hope that parents up and down the country are showing this disaster to their children and warning them in no uncertain terms - DO NOT GO ON THE ICE!
When I was a child the local park had an ornamental pond and as soon as the frosts started the ranger put up signs telling us to keep off the ice. It wasn't a deep pond and in summer we would use it to cool off - it was about waist deep. But falling in in winter could lead to instant shock and an inability to get out.
