A wild elephant in southern China picked up an American tourist with its trunk and threw him in the air, causing the man to suffer from fractured ribs and stomach injuries, an official said Monday.

Jeremy Allen McGill, who teaches English in the central Chinese city of Wuhan, was found unconscious around dusk on Thursday at the "Wild Elephant Valley" nature reserve in the Xishuangbanna region of Yunnan province.

"It wasn't clear why he was attacked," said an official with the Xishuangbanna foreign affairs office who would give only his surname, Chen.

McGill's abdomen and lungs were "seriously injured" and he had broken ribs, Chen said. He was hospitalized and had stitches up to 40 centimeters (15 inches) long on his stomach, said Chen, who had no details on McGill's hometown.
