WASHINGTON (AP) — Black men from around the nation are gathering on the National Mall to celebrate the 20th anniversary of the Million Man March and call for policing reforms and changes in black communities.

Nation of Islam leader Louis Farrakhan spearheaded the original march and will lead an anniversary gathering Saturday called the "Justice or Else" march.

In a statement, Farrakhan says he plans to deliver an uncompromising message and call for the U.S. government to respond to legitimate grievances.

Attention has been focused on the deaths of unarmed black men since the shootings of 17-year-old Trayvon Martin in 2012 in Florida and 18-year-old Michael Brown in 2014 in Ferguson, Missouri.

The original march brought hundreds of thousands of people to Washington to pledge to improve their lives, families and communities.
