Rhino deaths raise extinction fears

The discovery of three dead Javan rhinos has added urgency to efforts to save one of the world's most endangered mammals.

An electric fence was being built around a new sanctuary and breeding ground in Indonesia today as camera-trap footage was reviewed to get a better idea of just how many remain. The best estimate so far is around 50.

Wildlife activists, meanwhile, were joining discussions about relocating some of the five-ton animals to protect them from diseases or natural disasters.

Currently, all but a handful live in a densely forested national park in western Indonesia, making them all the more vulnerable.

The International Rhino Foundation says that "without drastic action, some rhinos could be extinct in the wild within the next 10 to 20 years"
