In England, three boys - aged 8, 10 and 11 - have died after falling into an icy lake in Solihull, outside Birmingham.
Firefighters and police officers worked together to pull them from the water, but they 'could not be revived.'
Another six year old boy was rescued but remains in a critical condition in hospital.
Fire and Rescue Area Commander, Richard Stanton, says it is heartbreaking.
"The boys' deaths are a tragedy beyond words and the thoughts and heartfelt sympathies of everyone here in the West Midlands Fire Service are with their families at this distressing time"
