A close friend of the main London Bridge Terrorist has been jailed for four and a half years today after making this ISIS propaganda video outside Windsor Castle pledging to kill 'non-believers'.

Taha Hussain, 21, from Slough, Berkshire, was in a group shouting 'Allahu Akbar' and 'baby butchers' at soldiers in the town's barracks.

He also pledged to topple a statue of Queen Victoria in the same way Saddam Hussein's fell in lraq in 2003 - but later told police he was in Windsor 'feeding the ducks'.

He and another extremist filmed themselves in a car outside the famous castle and at the nearby Coldstream Guards barracks as they made threats and vowed to 'liberate Windsor' saying: 'ISIS will last for ever'. Hussain was an associate of Khuram Butt, who went on to lead two other men on a vehicle and knife attack on London Bridge and in Borough Market in June, killing eight people. 

Hussain ran ran two Youtube channels and broadcast extremist material using Whatsapp and Telegram to circle of extremists and appeared on the notorious Jihadi Next Door documentary on Channel 4.

Among the material he shared was an ISIS guide to joining the fighting in Syria which advised followers to launch an attack in their own countries if they were prevented from making the journey.

He also spread terrorist propaganda which said politicians, police and soldiers were the 'best of all people to kill'. 

Judge Paul Dodgson told him: 'Most chillingly in the light of recent events there is a chapter containing advice to those who could not go to Syria.

'The advice includes to wait a few months and try again, steal from the kuffars [non-believers] and, most pertinently to the events we have endured this year, kill local kuffar in their own land.  Hussain and another friend filmed themselves in a car outside Windsor Castle and at the nearby Coldstream Guards barracks as they made threats and yelled ISIS slogans.

In court, the apprentice panel beater, who had become religiously observant at the age of 15, claimed he was in Windsor 'to feed the ducks.'

But, sentencing him to four and a half years in jail, the judge told him: 'The attitude that you then possessed is clearly demonstrated by the words of hatred that you used.'

He said the video 'demonstrates quite graphically what his state of mind was at the time, and his feelings towards his country are amply demonstrated in that video.
