Imams, ministers and a rabbi staged a "pray-in" demonstration Monday at Reagan Washington National Airport and asked an apology from US Airways for barring six Muslims from a Minneapolis to Phoenix flight last week. The religious leaders called for an end to racial profiling, saying it was unacceptable in America. Imam Omar Shahin, one of the six imams detained last Monday at the Minneapolis-St. Paul International Airport, said they had not done anything suspicious. The imams, who were returning from a religious conference, had prayed on their prayer rugs in the airport before the flight. After they boarded the flight, a passenger passed a note to a flight attendant. The men were taken off the airplane, handcuffed and questioned.
