I guess burning the American flag is a trick they picked up from Bill Ayers and the Weatherman.
Update: From RT.com;
South African police fired stun grenades at hundreds of protesters on Saturday who were demonstrating against US President Barack Obama’s visit to South Africa, according to AFP. Three loud bangs were heard as police tried to move the angry protesters away from the area. Obama’s visit to the country has caused some controversy among a coalition of trade union groups and left-wing political organizations which planned a “national day of action” to coincide with his visit. The groups have indicated that they are cynical about American foreign and trade policies, and that they feel Obama has done nothing to the advantage of South Africa, but merely continued American foreign policies, to which they had hoped for an end.
