OKLAHOMA CITY — Zookeepers in Oklahoma are celebrating the birth of rare Sumatran tiger twins.
Last week, the Oklahoma City Zoo announced that 11-year-old Lola gave birth to them on July 2.
Officials say the birth of the cubs is "a significant event" because the animals are critically endangered.
According to the zoo, there are approximately 500 left living in the forests of Indonesia.
The zoo says mom and the cubs are doing well.
Officials say they will remain out of public view so they can bond.
Their gender will be revealed in the coming weeks, the zoo said.
