An American internet company has been accused of being a 'safe haven for terrorists' after failing to pass on information which might have prevented the murder of soldier Lee Rigby.
Fusilier Rigby was mown down by a car and then stabbed to death by muslim converts Michael Adebolajo and Michael Adebowale in Woolwich in south east London last year.
An investigation by a Parliamentary watchdog, the Intelligence and Security Committee, revealed the two men featured in seven different investigations by MI5, MI6 and GCHQ but were regarded as low-level threats.
Adebowale expressed his intention to murder a soldier on an internet forum in the 'most graphic and emotive manner', said the report. But details only emerged after Fusilier Rigby's murder.
The internet firm was not named because information about Adebowale's postings were given to GCHQ on a confidential basis.
ISC chairman, Conservative MP Sir Malcolm Rifkind, said US-based internet companies do not co-operate with British intelligence agencies.
He also criticised the Secret Intelligence Service, MI6, after it was alerted by the Kenyan authorities when Adebolajo tried to join the Somalian terror group Al-Shabaab.
