Police in South Africa remains on high alert in Johannesburg’s Alexandra Township following clashes between local residents and migrants from other African countries. An organization has been set up to try to stop foreign nationals from running businesses in the area. Members of the Alexandra Dudula movement say the migrants are in the country illegally and are taking away jobs from locals. The BBC reports that the Dudula movement has been criticized for encouraging xenophobia and violence, but its backers say they are protecting livelihoods.
