Britain - New Evidence in London Terror Attack

From the Telegraph (UK).

One of the four London suicide bombers made numerous calls to a stolen mobile phone in Pakistan up to three days before the July 7 attacks.

Pakistani officials say they have traced the stolen phone after receiving requests from Britain's MI5 to investigate. They suspect that it was used by terrorists linked to the bombers, and then discarded after the London attacks.

The phone number was rung several times - as late as July 4 - by Shehzad Tanweer, one of the bombers who visited Pakistan more than six months ago along with Mohammad Sidique Khan, the cells's suspected ringleader. The disclosure has deepened suspicions that a "mastermind" based abroad was guiding the gang.

And

It emerged on Friday that seven terrorist suspects wanted over possible involvement with the London bombings are facing extradition from Pakistan to Britain under a new agreement. One is thought to have met one or more of the suicide bombers.

Whitehall officials refused to confirm details of the MI5 request to Pakistan for "operational reasons", but conceded that mobile phone calls, including some made abroad, were now central to the investigation.
