Three men were found guilty of terrorism offences on Monday, including a teenager believed by prosecutors to be the youngest Briton to be convicted of an offence under the Terrorism Act. Hammaad Munshi, 18, Aabid Hussain Khan, 23, and Sultan Muhammad, 23, were found in possession of "huge volumes" of terrorism material, including Al Qaeda documents and information on poisons and firearms, police said. Detectives said the men were "facilitators" who provided exclusive, up to date information on terrorist techniques, training, weapons and explosives. "These are not the actions of curious individuals, or even those who are sympathetic to terrorist objectives," said Detective Chief Superintendent John Parkinson, head of the Leeds Counter Terrorism Unit.
