South African President Cyril Ramaphosa voted in Johannesburg on Wednesday, with the ruling African National Congress (ANC) facing a challenge to its control of major cities in local government elections.

Zambia's incumbent President Hakainde Hichilema is among 14 candidates who have so far filed nominations for the August general elections in that country. 

The nominations are, however, still ongoing and are expected to close by the end of this week.
