Three boys in England have died after falling through a frozen lake into its icy waters, authorities said Monday. The victims, aged just 8, 11, and 12, were confirmed dead by West Midlands Police after they were pulled from the water in Solihull, central England, and rushed to hospital on Sunday. A fourth boy, aged 6, remained in a critical condition on Monday. On Sunday, officials said the children were all in cardiac arrest when they were pulled out of Babbs Mill Lake by rescue crews, and were “receiving advanced life support en route to hospital.” Witnesses initially reported seeing up to six children falling through the ice while at the site, sparking fears that two remained missing. “A number of children had been playing on the ice on a lake and had fallen through the ice,” West Midlands Fire Service area commander Richard Stanton said. Hours later, the total number of children who fell into the water remained unclear. Stanton said Sunday night that search operations had been called off, citing the water’s temperature among other factors. A West Midlands police spokesperson could not confirm whether authorities would be looking for anyone else. Temperatures in Solihull fell to around 30 degrees on Sunday.
