Twenty rare Siamese crocodiles hatch in zoo

One of the world's rarest crocodiles is clawing its way back from extinction in the wild, with the hatching of 20 eggs in Laos.
The eggs of the Siamese crocodiles were found floating on a bed of reeds in a lake in southern Laos in June, and were brought to the zoo for protection.
