The South African government, as well as Chad, Sanparks and African Parks confirmed in a joint statement the carcasses of a rhino bull and cow were found in the Zakouma National Park last Monday.
“We can confirm that the two rhinos were not poached, but the cause of their death is still unknown,” said the statement.
A specialist veterinarian is currently visiting Zakouma to conduct post-mortem examinations.
The other four rhinos are still alive and under constant observation.
The group of six black rhinos was transported from the Marakele National Park in Limpopo to the Addo Elephant National Park, 70km outside of Port Elizabeth, in January.

They were detained in Bomas for two months after their arrival at the park in Chad, before they were released in a temporary conservation area for another two months to adapt to their new environment.
The fence of the conservation area was lowered in August and the rhinos were free to explore the greater part of the park.
According to the statement, discussions are being held between the relevant role players to take precautions to avoid a similar incident with the remaining four animals.
Chad used to be the home of black rhinos and white rhinos, but due to poaching, the last rhino was seen in Zakouma in 1972.
