From the FBI Press Release:

“Luqman Ameen Abdullah did not surrender and fired his weapon. An exchange of gun fire followed and Abdullah was killed. An FBI canine was also killed during the exchange.

Abdullah was the leader of part of a group which calls themselves Ummah (“the brotherhood”), a group of mostly African-American converts to Islam, which seeks to establish a separate Sharia-law governed state within the United States. The Ummah is ruled by Jamil Abdullah Al-Amin, formerly known as H. Rapp Brown, who is serving a state sentence in USP Florence, CO, ADMAX, for the murder of two police officers in Georgia.”

H. Rapp Brown, formerly the “Justice Minister” of the Black Panther Party, and currently serving life in a supermax in Colorado, is identified as the leader of the larger org to which this little group belonged.
