Striking farm workers carry a placard demanding a minimum wage of 150 Rand (US$ 17) as they march towards police 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.
