Lusaka -

At least 52 Cape buffaloes in a herd crossing a river in Zambia's largest game reserve were killed in a stampede, wildlife authorities said on Tuesday.

The incident occurred on Friday in Kafue National Park, in the south of the country, which is home to thousands of Cape buffaloes.

“We have so far counted 52 buffaloes but there could be more as we suspect some might have been eaten by crocodiles,” said Readith Muliyunda, the spokesman of Zambia Wildlife Authority.

Muliyunda told that it was unusual for a stampede to cause so many deaths.

It is not clear what provoked the rush.

The vast park covers about 22 000 square kilometres. - Sapa-AFP
