US: Seven arrests over Chicago plot

Seven people suspected of plotting to blow up Chicago's Sears Tower and other targets have been arrested by the FBI.

They were seized during a raid by federal agents on a warehouse in northern Miami. No weapons were found.

The suspects include five US citizens and two foreigners, including a Haitian. They are said to be Muslim.

Reports say the group, which had no apparent links to international terror, had been infiltrated by a US agent posing as a member of al-Qaeda.

They were reportedly trying to buy weapons.
