Boston: The FBI has searched eight homes, mainly of anti-war protesters, in Minneapolis and Chicago as part of an investigation into "material support of terrorism", drawing condemnation from peace activists who said it was aimed at "harassing them”.
Six warrants were served yesterday in Minneapolis, Minnesota and two in Chicago, Illinois.
FBI spokesman Steve Warfield said the agency is not anticipating any arrests at this time.
"These were search warrants only," Warfield said.
"We`re not anticipating any arrests at this time. They`re seeking evidence relating to activities concerning the material support of terrorism."
The homes of Minneapolis anti-war activists Mick Kelly and Jess Sundin were among those searched.
Warrants suggested agents were looking for connections between local anti-war activists and terrorist groups in Colombia and the Middle East.
According to a report in CNN, activist Tom Burke in Chicago said he and others in Minnesota were served subpoenas to testify before a grand jury.
He also said computer hard drives were taken from locations in both cities.
Kelly said the FBI was "harassing anti-war organisers and leaders, folks who opposed US intervention in the Middle East and Latin America."
Among the activists are those involved with the Palestine Solidarity Group, the Freedom Road Socialist Organisation, the Twin Cities Anti-War Committee and Students for a Democratic Society, which was active during the Vietnam War.
Sundin of the Twin Cities Anti-War Committee told CNN agents took a hard drive, paper files, photos, a cell phone and her passport during a search of her Minneapolis residence.
Denying any wrongdoing, Sundin said she was given a subpoena to appear next month before a grand jury in Chicago. Sundin added that sending American weapons and troops abroad is not the solution to international problems.
"We agree the US should treat neighbours in peaceful ways," added Burke, pointing to conflict in the Middle East and Colombia.
"We think they (the FBI) are on a fishing expedition."
