ISLAMABAD, Pakistan - Authorities in Pakistan are looking into a connection between one of the London suicide bombers and two al-Qaida-linked militant groups here, including a man arrested for a 2002 attack on a church near the U.S. Embassy, two senior intelligence officials said Friday. The investigation is focusing on at least one trip that 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. They spoke to The Associated Press on condition of anonymity because of the secretive nature of their jobs.
