KABUL, Jan 5 (Reuters) - NATO troops in Afghanistan have reported seeing lots of children with toy guns, apparently given as presents at a recent Muslim holiday, raising fears of an accident if troops mistook a toy for a real gun. "We've had a lot of reports since Eid from troops on the ground of a lot of kids with toy guns," said a spokesman for the NATO force, Major Ian Clooney. Muslims celebrated the Eid al-Adha festival at the weekend marking the end of the annual pilgrimage to Mecca, when children traditionally get presents. "This is being taken seriously," Clooney said. "We've tried to get the message out so parents can educate their children. We can't afford to let accidents happen." NATO commands a force of about 32,000 in Afghanistan, battling Taliban militants and trying to ensure security for development.
