An ANC supporter wears a hat with pictures of South African president and leader of the ANC Jacob Zuma as she sits in the stands of the FNB Stadium in Soweto filled to capacity at the final ANC campaign rally on May 4, 2014.  South Africa's main opposition the Democratic Alliance on Sunday claimed activists of the ruling ANC stoned two buses filled with its supporters heading to Soweto for an election campaign concert. One of the buses was stoned near the FNB stadium, venue of the 2010 World Cup final, where the ruling African National Congress party is holding its final campaign rally on Sunday.
