A woman tries to stop a bulldozer from destroying her house in Lenesia, south west of Johannesburg. Earlier today protesters have burned tyres and blocked roads, after the government tore down houses built on plots that were illegally sold. The Gauteng provincial housing department said it had demolished 37 of 113 houses. The action came after a probe revealed that stands had been sold for amounts from 2,500 rand (225 euros) to 95,000 rand. South Africa faces a massive housing backlog with nearly two million people living in informal shacks.
