London bomber 'linked to al-Qaida in Pakistan'

Authorities in Pakistan are looking into a connection between one of the London suicide bombers and two al-Qaida-linked militant groups there, including a man arrested for a 2002 attack on a church near the US Embassy, two senior intelligence officials said today.

The investigation is focusing on at least one trip 22-year-old Shahzad Tanweer made to Pakistan in the past year, said the officials, who work at two separate intelligence agencies and are involved in the investigation.
