A protester throws a stone at the police during a strike by farm workers at De Doorns on the N1 highway linking Cape Town and Johannesburg January 9, 2013. Police fired rubber bullets and stun grenades at hundreds of striking farm workers who blocked a highway in the grape-growing Western Cape on Wednesday, the first clashes of a year likely to be marked by fractious labour relations.
