Three Bengal tigers were born at a zoo in the Paraguay capital Asuncion, its director said Tuesday. The cute trio, born Friday, weigh between 1 and 1.5 kilos (2.2 to 3.3 pounds) and are doing well, Maris Llorens told reporters. Their proud parents -- Turca and Kachima -- were taken in by the zoo last year after they were abandoned by a circus. The cubs have yet to be named, and Paraguayans have been asked to submit suggestions. According to Llorens, the birth of Bengal tigers in captivity is rare.
