PHNOM PENH (Reuters) - Cambodian authorities have cracked down hard on a new social menace — children flying kites in city parks. The pastime is hard on the grass, authorities said. So police — some of them armed — have been chasing children away from parks in the capital and confiscating kites from vendors in a heavy handed blitz on the flyers, the Phnom Penh Post reported. „We cannot even let two or three people play with kites in the park because then there will suddenly be 100 or 200 people flying kites, too,“ one security guard told the newspaper. Flocks of colourful kites, their tails streaming in rainy season breezes, have been flying over the city in recent weeks.
