Two military horses that bolted and ran miles through the streets of London after being spooked by construction noise and tossing their riders were in serious condition after undergoing operations, a U.K. government official said Thursday. The animals were among a group of four horses that broke free during routine exercises Wednesday near Buckingham Palace and caused chaos as they galloped loose through central London during morning rush hour. Two of the horses underwent operations and one was transferred to an equine hospital, the British Army posted on X.
