THE SUSPECTS

Shahzad Tanweer: The 22-year-old attended Leeds Metropolitan University, where he studied sports science and developed an interest in cricket. He has a younger brother and two sisters, and has always lived in the Beesten area of Leeds. His father was born in Pakistan and owns a fish and chips shop. Tanweer went to Lahore, Pakistan, for two months earlier in the year to study Islam, his uncle said. Forensic evidence has linked Tanweer to the blast near Aldgate, British police say.

Hasib Hussain: The 18-year-old has lived with his family in the Leeds suburb of Holbeck, where they lived for more than 20 years, according to neighbors. From September 1998 until July 2003, he attended Matthew Murray High School, completing vocational business studies. He reportedly became a more devout Muslim two years before the attacks, according to police who questioned neighbors. His driver's license and cash cards were found in the wreckage of the double-decker bus.

Mohammed Sidique Khan The 30-year-old Pakistani native originally lived in the same area of Leeds as Tanweer, but moved five months before the attacks to Dewsbury in West Yorkshire. He worked with disabled children while his wife, Hasina, was involved in education, neighbors said. The couple has an 8-month-old daughter. He is Muslim, although one neighbor, Imran Zaman, said he had never seen Khan at the local mosque. Documents belonging to Khan were found in the debris of the Edgware Road blast.

On Sept. 1, 2005, al Qaeda's No. 2, Ayman al-Zawahri, claimed responsibility for the July 7 London bombings in a video aired on Al-Jazeera that included a farewell statement by a Khan. Speaking English with a heavy Yorkshire accent, Khan said he had forsaken "everything for what we believe" and went on to accuse Western civilians of being directly responsible for the terror attacks that befall them.

It was the first explicit claim of responsibility for the blasts by the terrorist group headed by Osama bin Laden.

Germaine Lindsay, 19, a Jamaican-born Briton, has been identified by Scotland Yard as one of the suicide bombers who set off the deadly explosions in London. He died in the explosion between King's Cross and Russell Square Underground stations. Authorities believe that he was responsible for carrying out that attack.
