"GABORONE - The deaths of hundreds of elephants in Botswana this year which had baffled and alarmed conservationists were caused by toxins produced by cyanobacteria in water, officials said on Monday.
Cyril Taolo, deputy director of the Department of Wildlife and National Parks, told a news conference that the number of dead elephants had risen to 330, from 281 last reported in July.
The department’s principal veterinary officer Mmadi Reuben told the same conference that there were, however, still many unanswered questions."
