9/11 report finds key intelligence failings

US intelligence agencies failed to share key information about the September 11 hijackers with each other ahead of the terror attacks on New York and Washington, an investigation by congress has found.

Conversations were intercepted as early as 1999 showing two of the men were linked to a suspected al-Qaida facility in the Middle East, but the National Security Agency did not pass on this information to other agencies, said the report, which is due to be released today.
