TACTICS, BUT NOT THE PLANNERS:

London Finds Linked Bombs, a Qaeda Tactic (ALAN COWELL, 6/30/07, NY Times)

Security experts said that neither the bomb materials nor the cellphone triggering device was particularly sophisticated. Nor, said Sajjan M. Gohel, a counterterrorism expert with the Asia-Pacific Foundation, did the attack “seem to be very well planned.”

But the idea of a multiple attack using car bombs — a departure from the backpack suicide attacks of the London bombings of July 2005 — raised concerns among security experts that jihadist groups linked to Al Qaeda may have imported tactics more familiar in Iraq.
