Current Events

[In this picture, police are firing rubber bullets at mobs and protesters. Rubber bullets are rubber made bullets that hurt as much as real bullets but do not go through the skin or enter to skin and "bounces off" the person, though it hurts like a real bullet]
Just recently in South Africa, there have been mobs and protests directed at the foreigners in Johannesburg. At least 22 people were killed in the small village at the mobs attacked at, and the Red Cross estimates that at least 3,000 more were displaced. The police also arrested at least 200 people for offenses including rape, murder, looting, and destruction of property.
"Police said those behind the attacks accused the foreigners of stealing jobs, criminal activities, and benefiting from social services -- such as free housing --meant to benefit South Africans. Police said at least one foreigner was burned alive over the weekend, while others had their houses torched, their shops looted and their possessions stolen. Many have sought refuge at police stations." [CNN]
They attacked those small villages "where locals are jobless, hungry and in need of basic services such as clean water, sanitation and housing" [CNN]. These attacks were meant to drive out the foreigners, like escapes from Zimbabwe from South Africa.
Its amazing that after everything that happened after the apartheid nationality is still a problem in South Africa.
