Update, Sept. 13: The bottom of this article has been updated with a statement from the Botswana government.
At least 87
elephants were killed for their tusks near the Okavango Delta wildlife sanctuary in Botswana—the largest scale of poaching deaths ever seen in Africa, according to conservation nonprofit Elephants Without Borders.
They "discovered the alarming rate while flying the Botswana government aerial [elephant] census," the organization
said in a Facebook post.
