MIAMI, Florida (CNN) -- Seven people are in custody after a sweep by law enforcement authorities in connection with an alleged plot against targets that may have included the Sears Tower, officials told CNN on Thursday.
Officials said no weapons or bomb-making materials had been found in the searches in the Miami, Florida, area by FBI and state and local law enforcement officials. The city is under no imminent threat, according to the FBI.
Law enforcement sources told CNN that the arrests disrupted what may have been the early stages of a domestic terrorist plot to attack the Sears Tower in Chicago, Illinois, the FBI building in Miami, and possibly other targets.
The 110-story Sears Tower, in Chicago, Illinois, is the world's third-tallest building and the tallest in North America.
Law enforcement sources told CNN that some of the suspects are members of a radical African-American Muslim group and that at least one had taken "an al Qaeda oath." They had carried out surveillance on the Sears Tower and FBI building in Miami, the sources said.
Sources told CNN that the arrests culminated a month long undercover operation. The suspects believed they were dealing with an al Qaeda operative, but the person was actually a government informant, the sources said.
The FBI said one search warrant was executed in a warehouse near a housing project in Liberty City, a predominantly black and low-income area of Miami.
Residents living near the warehouse told The Associated Press that the men taken into custody called themselves Muslims and had tried to recruit young people.
