(CNN) -- The leader of a group of African-American converts to Islam was fatally shot in Detroit, Michigan, Wednesday, federal authorities said.
Luquman Ameen Abdullah was one of 11 men charged Tuesday with conspiracy to commit federal crimes, including theft from interstate shipments, mail fraud to obtain the proceeds of arson, illegal possession and sale of firearms, and tampering with motor vehicle identification numbers, the FBI said in a news release.
He had been seeking to establish a separate Sharia-law state in the United States, the FBI said.
Eight of the men have been arrested. At one location, four of the suspects surrendered, but Ameen Abdullah fired his weapon instead, the release said. "An exchange of gunfire followed and Abdullah was killed," it said.
Also killed was an FBI dog.
In a 43-page criminal complaint filed Tuesday in U.S. District Court in the Eastern District of Michigan and unsealed Wednesday, authorities said the arrests were made based on information gleaned from confidential sources identified only as S-1, S-2 and S-3.
"S-1 heard Abdullah encourage his followers to 'pick up guns and do something' rather than try to achieve their goals through peaceful means," the complaint said.
S-2 recorded a conversation on December 12, 2007, in which Abdullah said, "I got some soldiers with me, so it's not like I, I don't have, you know, nothing. Brothers that I know would, you know, if I say 'Let's go, we going to go and do something,' they would do it," the complaint said.
S-3 said that, on March 21, 2008, Luqman Abdullah told him "that the FBI is the enemy of Islam," the complaint said. "Abdullah stated something to the effect, 'If they are coming to get me, I'll just strap a bomb on and blow up everybody.'"
The other men charged were identified as Mohammad Abdul Bassir, aka Franklin D. Roosevelt Williams; Muhammad Abdul Salaam; Abdul Saboor; Mujahid Carswell; Abdullah Beard; Mohammad Philistine; Yassir Ali Khan; Adam Hussain Ibraheem; Garry Laverne Porter; and Ali Abdul Raqib.
The U.S. Attorney's Office in Detroit said hearings were scheduled for Thursday at 1 p.m. ET for Salaam, Saboor, Porter, Beard, Ibraheem and Raqib.
The defendants "are members of a group that is alleged to have engaged in violent activity over a period of many years, and known to be armed," the FBI said.
The complaint was filed by the FBI's counter-terrorism squad in the Eastern District of Michigan.
