Britain has vowed to hunt down anyone associated with last week's devastating attacks on US landmarks who may be living in Britain.
Minister for Europe Peter Hain said intelligence was being shared with US investigators seeking those responsible for the suicide hijackings that killed thousands in New York, Washington and Pennsylvania.
The Daily Mail newspaper reported this week that five of the hijackers had trained in Britain, and that the FBI had passed names and details to British police.
The paper said "dozens of addresses across Britain will now be raided as police Special Branch and anti-terrorist officers try to trace the movements of the five and everyone they contacted".
A Scotland Yard spokeswoman declined to discuss the article.
