S. African police block march by schoolchildren

Police fired tear gas to halt a march by some 8,000 Colored schoolchildren here Tuesday as a protest against racially separated education in South Africa. Riot police blocked off a road as children from several schools marched toward a planned meeting point. This was the first major incident since a classroom boycott by pre-dominantly Colored -- the term used here for people of mixed race -- teenagers in Cape Town last week. Since then, thousands of pupils in other major centers have joined the protest.
