Canadian police arrested two Muslim men Saturday wanted by the FBI because of their relationship to a Detroit mosque, authorities said.

Yassir Ali Khan, 30, and Mohammad Philistine, 33, were being held in Windsor, Ontario, pending an extradition hearing, Canwest News Service reported. They were arrested by Windsor police and the Royal Canadian Mounted Police.

The FBI charges that Luqman Ameen Abdullah, a leader at the mosque who died in a shootout with agents at a warehouse in Dearborn, Mich., this week, headed a group that wants to establish a separate Sunni Islamic nation within U.S. borders. The group allegedly raised money by selling stolen goods.

Eleven people were indicted after an FBI sting operation, the Detroit Free Press reported.

Abdullah's son, known both as Mujahid Carswell and Mujahid Abdullah, was arrested earlier this week in Windsor.
