Kite flyers arrested in Pakistan 
 
Despite the ban the skies above Lahore were filled with kites

More than 500 people are reported to have been arrested in the Pakistani city of Lahore for flying kites.

Kite flying is a traditional part of a festival marking the advent of spring in Punjab, but on Thursday the Pakistani authorities introduced a ban.

The prohibition came in after a number of deaths, mostly in Lahore, caused by glass-coated or metal kite-strings.

Families of the seven victims protested last week, demanding that a Supreme Court uphold a ban on the sport.

Similar bans have been imposed in previous years.

They must have some pretty strong winds in Pakistan to be lifting metal kites coated with glass string.
