Intelligence chiefs have conceded they know little about the planning of the attack or whether al Qaeda was involved.

In a report for Tony Blair and senior ministers – leaked to The Sunday Times – MI5 says: «We know little about what three of the bombers did in Pakistan, when attack planning began, how and when the attackers were recruited, the extent of any external direction or assistance and the extent and role of any wider network.»

The report by the Joint Terrorism Analysis Centre (JTAC), says MI5 still does not know if al Qaeda was behind the July 7 and July 21 atrocities.

The report says there is still no intelligence to link the two plots.

It adds: «Whilst investigations are progressing, there re2_kommentar significant gaps in our knowledge.»

The report was delivered in October. But sources have reportedly said the situation has changed little since then.(itn)
