Botswana opens inquiry into unprecedented surge in death of elephants
Botswana is investigating the unprecedented deaths of hundreds of elephants since May.
The government said three laboratories in Canada, South Africa and Zimbabwe would be asked to process the samples taken from the dead elephants.
More than 350 elephant carcasses have been spotted in Botswana’s Okavango Delta in the past two months.
No-one knows why the animals are dying in Botswana
The country is home to a third of Africa’s declining elephant population.
