A bitter little local dispute over a school playground in the Kenyan capital Nairobi has seen pictures of uniformed schoolchildren being teargassed by police go nationwide, and now internationally.<br /><br /> Several pupils and a police officer were injured at Langa’ta road primary school after pupils and some teachers and parents protested against what they claim is an illegal land grab by a developer who wants to build a car park. Surrounding streets were filled with crying children fleeing the violence.<br /><br /> The government says the police will be investigated for an inappropriate use of force, and at least two officials have gone on record promising the land will be returned.<br /><br /> Eventually a hastily-built dividing wall was torn down by hand and pupils reclaimed the land and started a football match.
