An animal welfare group is to launch a campaign against US fastfood chain Kentucky Fried Chicken. People for the Ethical Treatment of Animals (PETA) claims that KFC is guilty of cruelty to the chickens that it rears. PETA has accused the fastfood chain of using what it calls "crude and ineffective" methods of killing birds such as electric stunning and throat slitting. The animal rights group is calling for the use of gas to knock out the birds before they are slaughtered.
