'Born-free' South African voters cast ballots

South Africans are voting in general elections as the country marks 20 years since the end of white minority rule.

The African National Congress is tipped to win, returning President Jacob Zuma for a second five-year term.

The BBC's Nomsa Maseko visited the township of Diepsloot, where thousands of people were queuing to vote, including some who were "born free" - after the end of apartheid.
