Kite flying at dusk from a rooftop in the Old City of Lahore. Pakistan's biggest annual festival is Lahore's spring celebration of Basant. Originally a Hindu festival which culminated in a weekend of non-stop kite flying, kite flying has recently been banned for safety reasons. Millions of people took to the city's parks and rooftops, cutting their opponents out of the sky with their kite strings, which were often coated with ground glass or metal filings. These proved fatal to motorcyclists, many having their throats cut by fallen strings. Other dangers include electrocution, and falls from roofs and traffic accidents as people, particularly youngsters, gaze skywards and pursue falling kites with long poles. Bans on kite flying have proved hard to thousands of people who made the paper and cane kites, and the coated strings that endanger lives.
