Pakistan holds militants possibly linked to London bombers

Police in Lahore today said they were holding some Islamic militants who may have had links with the suspects in the London suicide bombings, as investigators try to assess whether extremists in Pakistan were involved in the July 7 attacks.

The revelation came a day after a senior immigration official said three of the four suspected bombers travelled last year to the southern port city of Karachi. All three were Britons of Pakistani origin.
