Pakistani ties to London's 7/7 attacks?

LONDON, Feb. 3 (UPI) -- Phone records connected to deadly 2005 bombings in London show plotters had coordinated before the attacks with Pakistani contacts, an inquiry heard.

Four suicide bombers detonated explosive devices on British trains and buses July 7, 2005, killing 52 people.

Authorities investigating cellphone records found calls made from telephone booths in Rawalpindi and bomber Mohammad Sidique Khan, who detonated his explosives on the London Underground.

Most of the calls came from different locations in Rawalpindi but came within minutes of each other. Police investigators said they suspect Khan gave his Pakistani contacts phone numbers connected to the plot but never actually called Pakistan himself, the BBC reports.

Most of the calls were made in May and June 2005, the report adds.

British intelligence agency MI5 had Khan on its radar ahead of the attacks, though analysts had determined he wasn't a likely threat. Lawmakers criticized police for not taking peripheral players into consideration.

British authorities dismissed claims that al-Qaida played a direct role in the attack, though radical Yemeni cleric Anwar al-Awlaki allegedly inspired the cell responsible for the July 2005 attacks.
