The October 2004 U.S. federal grand indictment against Babar Ahmad, 31, accuses him of conspiring to provide support to terrorists, including helping to ship gas masks to the Taliban and using U.S.-based Web sites to raise money for Chechen Muslims.
Britain's Home Secretary Charles Clarke ordered Ahmad extradited to face trial in Connecticut, where he faces life imprisonment if convicted of any of the terror charges against him. One of the Internet service providers used by Ahmad had headquarters in the state, The Times of London said.
A statement from Ahmad in prison said it "should only come as a surprise to those who thought that there was still justice for Muslims in Britain."
His case is the first to be handled under a U.S.-British extradition agreement reached two years ago, which eliminated a requirement that the underlying evidence supporting the charges be presented in support of an extradition request.
