A man kept a vast library of terrorist instruction manuals on how to make bombs and suicide vests, the Old Bailey has heard. Musse Yusuf (31) allegedly stored more than 200,000 files relating to topics ranging from waging guerilla war to fitness training for al-Qaeda recruits. The titles included The Mujahideen Terrorist Handbook, Instructions on How to Attack Jewish People, The al-Qaeda Manual and Promoting Jihad.

Yusuf, who is Somalian, was arrested by police at his home in Higgs Close, Crown Hills, Leicester, at 6am on May 28, 2008.

Prosecutor Max Hill said: "These two hard drives were found to contain very large quantities of material. They are terrorist videos and terrorist manuals or handbooks. The videos contain practical information on the making of suicide vests, improvised explosive devices or bombs and the manuals are entitled the Mujahideen Terrorist Handbook and the Mujahideen Explosives Handbook. Among this material was material that suggested support for the cause of al Qaeda in Iraq and Afghanistan. The Crown say this material contains wide-ranging instructions on how to carry out military activity through the use of bombs, guerilla warfare, firearms, improvised explosive devices among many others."
