LONDON, Aug 19: Aabid Khan, Sultan Muhammad and Hammad Munshi, all three presumably Britons of Pakistani origin, were sentenced on Tuesday by a British court to serve varying prison terms for possessing or preparing documents promoting terrorism.

Mr Khan, 23, a former fast food restaurant worker from Bradford described as a ‘key players’ in radicalisation of the youth, was arrested at Manchester Airport in June 2006 on his return from a trip to Pakistan. He has been sentenced to serve a 12-year prison term.

Sultan Muhammad, 23, Khan’s cousin and also from Bradford, was sentenced to 10 years in jail.

Hammaad Munshi, 18, from Dewsbury, Britain’s youngest convicted terrorist will be sentenced next month.

He was just 16 when he was arrested on his way home from school. Police later found a guide to making napalm on his computer.

He was found guilty of making a record of information but cleared of a possession offence.

A night sorter for the Royal Mail, Sultan, was convicted of three similar charges and one of making a record of information likely to be useful in terrorism.

Prosecutor Simon Denison said evidence showed Khan had a “deep commitment to and involvement in violent jihad”.

This included “inciting others to take part in it and arranging for himself and others to attend military training in Pakistan in preparation for going to fight and, inevitably, to kill”.

He said all the men had amassed computers, CDs and books that “were the necessary tools of their trade, possessed to be used in furtherance of that violent cause”.

Two people in the public gallery were seen to be escorted out by court staff after the sentences were handed down. One was heard shouting and the other appeared upset.
