Record in rhino killing

341 rhinos have been killed so far in 2011 already passing last years record  of 333.
WWF says the spike in poaching in Africa and South Asia is becase of increased demand for rhino horn in Vietnamese  medicine.Poachers sawed off a rhinos horn leaving the animal to bleed to death.
In the five years up to 2005 an average of 36 rhinos were killed each year in South Africa.
The WWF said law enforcement efforts were increasing but were not enough to stop the smuggling and sale of their horns by organised crime rings.
