A proposal to bless South Africa's World Cup stadiums by slaughtering a cow in each one has caused concern among animal rights activists. The Makhonya Royal Trust, which put forward the idea, described the cattle killing ritual as a "true African" way of blessing the 2010 tournament. Government minister Sicelo Shiceka has promised to lobby football's governing body, Fifa, in support of the plan. But animal rights groups have demanded to be consulted over the plans. The row comes as a South African judge refused to stop a separate traditional Zulu bull-killing ceremony from going ahead on Saturday, instead calling on parliament to look at the issue. The National Council for the Prevention of Cruelty to Animals (NSPCA) has written to Fifa over the World Cup issue. The BBC's Mohammed Allie in Cape Town says the NSPCA does not object to the ritual slaughter of animals.
