COPENHAGEN, Denmark (AP) — Saying it needed to prevent inbreeding, the Copenhagen Zoo killed a 2-year-old giraffe and fed its remains to lions as visitors watched, ignoring a petition signed by thousands and offers from other zoos and a private individual to save the animal.

Marius, a healthy male, was put down Sunday using a bolt pistol, said zoo spokesman Tobias Stenbaek Bro. Visitors, including children, were invited to watch while the giraffe was then skinned and fed to the lions.
