The former president of Tanzania is reported to be fine after surviving a car crash in Johannesburg, South Africa, Thursday.

Former President Ali Hassan Mwinyi was riding in a convoy of 10 former African presidents when his car collided with a vehicle carrying Ghana's former president, Jerry Rawlings, and his wife, Nana.

Both Mr. Mwinyi and Nana Rawlings were taken to local hospitals. Mr. Mwinyi was examined and released, while Ms. Rawlings was treated for slight injuries.

African media reports say the accident happened as cars in the convoy swerved to avoid another accident on the road.

The former heads of state were traveling to a conference at Witwatersrand University to discuss encouraging investment in Africa and the continent's image in the American media.

The convoy included former presidents from Benin, Botswana, Burundi, Cape Verde, Kenya, Mauritius and Zambia.
