A Swedish zoo has killed nine healthy lion cubs over the last six years because they became 'surplus animals', its CEO has revealed.
Bo Kjellson said Borås Djurpark, in western Sweden, killed the cubs because they could not be sold or moved and because 'aggression became too big' in the group of lions.
He also said more of the gracious predators may be 'put to death' if they cannot be sent elsewhere and do not settle in the pride.
Discussing the cubs killed since 2012, Kjellson told Swedish broadcaster SVT: 'I think that they were killed after two years.'
He added: 'At that time we had already tried to sell or to relocate them at other zoos for a long time but, unfortunately, there were no zoos that could receive them - and when the aggression became too big in the group we had to remove some animals.
'And it had to be them.'
According to Espressen, the lions put down were named Potter, Weasley, Simba, Rafiki, Nala, Sarabi, Kiara, Kovu and Banzai.
