Four white lion cubs have been born at the Belgrade Zoo.
A white lioness gave birth Monday to the playful cubs, who are now important new members of the lion family at the zoo in the Serbian capital.
Nadja Radovic, who works with the lions, said Wednesday that all four cubs are doing fine. She says they have been accepted by their mother.
The zoo now has six lion cubs, a 1-year-old and four adult lions, three of whom are white.
White lions have become the zoo's greatest attraction.
