Hungry monkeys on the central Chinese mountain of Emeishan have attacked numerous tourists in recent weeks, according to reports.
In most cases the tourists themselves are to blame for the problem, says Zhou Shurong from the Ecological Monkey Area project.
"Tourists have in the past made the mistake of offering food to the monkeys and openly carrying foodstuffs with them," Zhou says. "The monkeys have become used to it in recent years and have become more aggressive."
Around 1,000 monkeys live in the wild on the Emeishan, one of the four holy Buddhist mountains in China.
A 23-year-old German student reports that she was attacked while sitting on the terrace of a Buddhist monastery. One animal grabbed her bag of food from her hand while another monkey snatched a carton of milk, tearing it open with its teeth and then pouring it over its head.
