South Africans are expected to take to the streets in their thousands this week in a series of demonstrations against President Jacob Zuma.

Anger has built across the country since Mr Zuma, 74, fired nine cabinet members, including his highly respected finance minister Pravin Gordhan, 67.

A social media campaign dubbed "Black Monday" that went viral at the weekend called on South Africans to wear black clothing on Monday as a demonstration against Mr Zuma.

The largest protests is due to held in Johannesburg this Friday with the main opposition party, the Democratic Alliance, calling on other political parties, unions and civil society movements to march to the ANC's city centre headquarters, Luthuli House.
