A Danish zoo that received death threats after it killed a young giraffe last month has now euthanized four lions.
The Copenhagen Zoo said Tuesday it put down two older lions and their two 10-month-old cubs to make room for a new male lion.
The older lion and lioness were euthanized as part of a generational shift, it said. They were about 16 years old, the Copenhagen Post reported.
The four lions were put down Monday after the zoo failed to find a new place for them to live, a spokesman told the AFP news service.
