These boys are professional camel jockeys.

They are the subject of complaints from human rights advocates, who say young children should not be put astride large animals for sport. They allege that some camel jockeys essentially are slaves, sold into the sport from poor countries like Sudan and, more often, India, Pakistan and Bangladesh.

On the most part, the children enter Kuwait with men claiming to be their fathers on a visitors visa and work through the racing season. Human rights advocates say some or all of these may be slave traders.

The Protection Project, a group at Johns Hopkins University that follows illicit trafficking of women and children around the world, has found evidence of a black market for camel jockeys in India, Bangladesh and Pakistan, said it's co-director, Mohamed Mattar. Boys are bought and sold in those countries and sent to Dubia, in the United Arab Emirates and home to the Middle East's most famous camel stables, he said. They sell for between $500 and $1000, and their families are compensated at a rate of $120 a month while they are gone, he said.

Last year, a U. S. State Department report on the modern slave trade cited examples of boys being taken from Pakistan, India, Bangladesh and Sir Lanka and sold for use in camel races. Reports like these seem to be having an effect on the sport. Dubai passed a law requiring camel jockeys to be at least 15 years old and weigh at least 45 kilograms. Saudi Arabia now requires jockeys be 18 or over.
