GABORONE (Reuters) - The number of elephants found dead in Botswana's Okavango Panhandle has risen to 275 from 154 reported two weeks ago, the government said on Thursday.

Authorities are investigating the unexplained deaths over the past months. Poaching has been ruled out as the carcasses were found intact.
