BEIJING - A Siberian tiger which had been freed by Russian President Vladimir Putin has returned to his homeland two months after crossing the border to China, state media said Wednesday. Kuzya, one of three tigers released into the wild by Putin, arrived back on his native soil Tuesday, the official Xinhua news agency reported, citing the Forestry Department of northeast China’s Heilongjiang province. But the endangered feline may not be gone for long, a senior Chinese forestry administration official said.
