Nation of Islam leader Louis Farrakhan is calling upon black people to unite and help redevelop Detroit. Farrakhan's remarks came Sunday as the Chicago-based movement wrapped up its four-day Saviour's Day convention in Detroit, which has a black majority population. Farrakhan, 82, told a crowd at Joe Louis Arena: "Detroit can be a great, great city again." He says "opportunity is here, but the disunity is also here." "Detroit can be the new mecca," Farrakhan said. "It can be great, great city. And it's 83 percent black." His speech, entitled "Divine Instructions: Commands for 2016," was streamed live on the National of Islam website.
