Activists gather as they take part in a protest against Rhinoceros poaching outside the Chinese embassy in Pretoria, March 29, 2012. Four staff members at South Africa's flagship Kruger National Park have been arrested on suspicion of killing rhinos and selling their horns to criminal syndicates, the park service said on Wednesday. Home to more than 90 percent of the continent's rhinos, South Africa is on the front line of a worsening war with poachers who send the horns to China and Southeast Asia for use in traditional medicine.
