Endangered female tiger killed by potential mate at London Zoo

A critically endangered female tiger died after being attacked by a prospective mate at London Zoo. Melati, a seven-year-old Sumatran tigress, was killed during her first encounter with 10-year-old Asim, a Sumatran tiger. Zoologists had hoped the two tigers would breed as part of a Europe-wide tiger conservation program for the endangered Sumatran subspecies.
