A Bradford CCTV operative who disseminated terrorist videos was told by a judge that he had acted as a "propagandist for Islamic State" as he was jailed for 12 years.
Asim Majid, 30, possessed and shared graphic films including videos which depicted suicide bombings, guidance on how to use a knife to kill, and images of dead soldiers, some of which were shared among a group of "trusted contacts".
Leeds Crown Court heard how the material was designed to inspire others to "fight for the cause of Islamic State".
Prosecutors told how the father-of-one owned a publication, titled How To Survive In The West, which promised to teach readers "how to be a secret agent who lives a double life, something which Muslims will have to do to survive in the coming years".
Following a two-week trial, Majid, of Cranbourne Road in Bradford, was convicted of two counts of possessing documents likely to be useful to a person committing or preparing an act of terrorism, as well as eight counts of disseminating terrorist publications.
He was also found guilty by a jury of a single charge of transferring money knowing that it may be used for terrorism.
The court heard how Majid sent £280 to a contact in Pakistan earlier this year, and although the purpose of funding was still "shrouded in mystery", the recipient came to own an AK47, a weapon he had discussed with the defendant.
Sentencing him on Thursday, Judge Tom Bayliss told the defendant:
The judge added:
During the trial, prosecutor Simon Davis told jurors:
The prosecutor explained how one of the films Majid owned was "particularly graphic and gruesome", providing guidance on how to stab, cut and kill enemies, using an actual human as a demonstration.
Mr Davis said that the video went on to demonstrate how to make a bomb, while another film depicted "fighters engaged in martyrdom".
Frida Hussain, defending, told how Majid's family had been adversely affected by his actions, and added that the defendant had simply copy and pasted links to the material he was sharing, arguing that he may have been unaware of how graphic some of it was.
