Victims of Tulsa massacre remembered in Oklahoma ceremonies

The centenary of a 1921 massacre targeting Tulsa's prosperous African-American community in the district of Greenwood, known as "Black Wall Street." After a black man was accused of assaulting a white woman, an allegation that was never proven, white rioters gunned down blacks, looted homes and set fire to buildings block by block. More than 1,000 buildings were destroyed.
