South African President Jacob Zuma says the governing party will not tolerate violence as 30 of his supporters appear in court Monday after a clash with opposition supporters.

The African National Congress members were arrested Saturday after a clash with members of the Economic Freedom Fighters led by expelled ANC firebrand Julius Malema at Nkandla, in KwaZulu-Natal.

They threw stones at the EFF members who handed over a house to a woman in the area. Zuma's private homestead is located in Nkandla, and is at the center of a major political storm after the government admitted using more than $20 million (200 million rand) of taxpayers' money to finance alleged security upgrades. The upgrades included a swimming pool and a small shop, among other luxury refurbishments.
