An ice-skating bear with a touring Russian circus has killed a circus manager and seriously injured a trainer in the Kyrgyz capital, Bishkek. Kyrgyz officials said the bear turned on the manager, 25-year-old Dmitry Potapov, during a rehearsal. The bear, who had skates on at the time, severely mauled another circus worker who tried to rescue the manager. Kyrgyz police shot and killed the bear when they arrived on the scene. It is not clear what caused the attack.
