Twelve more elephants have died in Zimbabwe, taking the total death toll from a suspected bacterial infection outbreak to 34, wildlife authorities said Monday.

“A total of 34 carcasses have been found… but some others have not been located,” Zimbabwe Parks and Wildlife Management Authority director Fulton Upenyu Mangwanya told parliament.

The animals died between August 24 and September 23 this year in and around the wildlife-rich forests between the famous northwestern Hwange National Park and the town of Victoria Falls.
