Details have emerged of the background of some of the British residents named in connection with the alleged terror plot to blow up UK flights.
| Arrests of terror suspects have sparked a massive security alert
They range in ages between 17 and 36 and are from various addresses in East London, Buckinghamshire and Birmingham.
Five live in the Buckinghamshire town of High Wycombe and three of those held have recently converted to Islam.
The list includes a security guard, a science student and a university drop-out who works for a music company.
Leading human rights lawyer and chair of the Muslim Council of Great Britain's legal affairs committee Khalid Sofi told BBC News the Muslim community had felt "shock and disbelief" at the arrests.
Mr Sofi said if the security services had indeed disrupted a genuine terrorist plot this would be very welcome, but it was important any evidence against the suspects was presented to their lawyers as soon as practically possible.
"Due to the international dimension to this case, it may take more time to assemble evidence," Mr Sofi said.
He is also concerned the enormous media coverage may have created an adverse impression of the suspects.
Abdul Waheed, 21, was arrested at a house in Hepplewhite Close, High Wycombe.
He had changed his name from Don Stewart-Whyte about six months previously, according to neighbours.
Another suspect, Osman Adam Khatib, 19, has lived in Walthamstow all his life.
He is described by a friend as having recently become very serious in his adherence to Islam.
One of the suspects has recently become a father and worked in security at Heathrow Airport.
Another is well-known for political activism at his university in East London. He is also a football fan and keen follower of Liverpool.
One of the men arrested in east London, the son of an architect, is a talented football player who works for a music company.
A British citizen arrested in Pakistan in connection with the alleged terror plot has been named as Rashid Rauf, described by the Foreign Ministry in Islamabad as a key suspect.
He is thought to be related to Tayib Rauf, 22, of Birmingham - another of the suspects arrested in Britain.

It has been reported today that the woman, who has not yet been named, is the wife of Muslim convert Oliver Savant. Eye witnesses described her as five foot tall with braided hair.
One witness said: "I heard a man shout and then the door was knocked through. I looked out of the window and saw a team of armed officers - wearing helmets and goggles - pour out of a black unmarked Mercedes people carrier.
"There were another two vans full of police wearing bullet-proof vests. And there were two guys who looked like intelligence agents who were controlling things."
In another raid, a young woman and her six month-old baby was taken into custoday.
It is believed that terrorists were planning to use liquid explosives to blow up the aeroplanes and as a result, airport security checks are forcing mothers to taste their bottles of baby milk before boarding.
