Over 100 hippos have died in Namibia in a remote national park in the past week, the country's environment minister said on Monday, warning that anthrax could be to blame.

Images from the Bwabwata national park in northeast Namibia showed dozens of lifeless hippos, some flat on their backs, others with just their heads visible above murky water.

"Over 100 hippos died in the past week. The cause of death is unknown but the signs so far show that it could be anthrax," Pohamba Shifeta told AFP.

He said the toll could be higher as crocodiles might have eaten some of the carcasses.

"Our veterinary services are currently working at the area to determine the cause of death. Once we have the results of the cause of death than we can decide on the way forward," Shifeta said.

Anthrax is a bacterial disease commonly associated with arid climates like the African savannah where it kills game, cattle, and sometimes humans.

Government officials estimated that Namibia's hippo population was around 1,300 before the mass death.

The minister added that he would be alarmed if there were any further hippo deaths at the national park which is one of the country's foremost tourist attractions.
