African-American farmers have staged a massive protest in Washington
DC calling on the US government to deliver on cash payments promised to
the group years ago.

In 1999, black farmers won a landmark case that granted them a
billion-dollar compensation settlement on the grounds of racial
discrimination by then US authorities.

But now the group says that tens of thousands of African-American farmers have not received the funds that they were promised.
