WORLD IN BRIEF : MEXICO : Panda Birth Marks Milestone for Zoo

Chia Chia, a giant panda on loan from the London Zoo, has fathered a tiny cub born to his Mexican mate Tohui. Veterinarians and panda keepers were maintaining a round-the-clock watch on the cub at the Chapultepec Zoo. The cub, whose sex isn’t yet known, weighed 4.2 ounces and was four inches long at birth Sunday. The new cub is the first offspring for Tohui, who was the first panda born outside China to survive. She was born July 21, 1981, and is one of four surviving offspring from a pair China gave the country in 1975.
