Protesters chant slogans during clashes believed to be linked to recent anti-foreigner violence in Reiger Park informal settlement, east of Johannesburg May 20, 2008. South Africa's police and the ruling ANC party intensified efforts on Tuesday to quell deadly violence against foreigners and a government minister said the unrest could damage the key tourism sector. At least 24 people have been killed in over a week of violent attacks on African migrant workers who are accused by many in South Africa's poor townships of stealing jobs and fuelling a wave of violent crime. \rREUTERS/Siphiwe Sibeko (SOUTH AFRICA)
