Pictures of the Week

A local man throws rocks at South African police in the Reiger Park informal settlement outside Johannesburg Monday May 19, 2008. Mobs rampaged through poor suburbs of Johannesburg in a frenzy of anti-foreigner violence over the weekend, killing at least 12 people, injuring dozens and forcing hundreds to seek refuge at police stations. The attacks capped a week of mounting violence that started in the sprawling township of Alexandra. Angry residents there accused foreigners, many of them Zimbabweans who fled their own country's economic collapse, of taking scarce jobs and housing. . (AP Photo/Jerome Delay)

Women from the Pro-independence Polisario Front rebel soldiers are seen during a military parade in the Western Sahara village of Tifariti, Tuesday May 19, 2008 to celebrate the 35th anniversary of the Polisario Army. After Spanish colonizers left Western Sahara in 1975, Morocco and Mauritania went to war over it. By 1979, Mauritania had pulled out and Morocco had taken over. But fighting continued between 15,000 Saharaui's Polisario guerrillas and Morocco's U.S. equipped army. A U.N. negotiated truce in 1991 called for a referendum on the region's future, but that vote never happened. (AP Photo/Daniel Ochoa de Olza)

An unidentified man buys cooking oil on the streets of Highfileds in Harare, Zimbabwe Tuesday, May, 20, 2008. The cooking oil is made affordable by repackaging into smaller bottles and containers. A third of the population has fled Zimbabwe in recent years as the country confronts chronic shortages of food, medicine, fuel and cash precipitated by the government's seizure of white-owned farms that once produced enough to feed the country and export to neighbors. The government this month introduced a half-billion Zimbabwe dollar note in efforts to deal with runaway inflation that unofficial estimates put at 700,000 percent a year.
