A young Islamic State fanatic who filmed himself mocking "baby butchers of the Muslims" as he drove past British Army barracks is facing jail for spreading terrorist propaganda.

Taha Hussain, 21, of Langtree Avenue, Slough, attended Islamic "road shows" and became increasingly extreme in the two years before his arrest in August last year, the Old Bailey heard.

Over 11 months, Hussain distributed videos and audio files on topics including Charlie Hebdo and the Paris attacks as well as a copy of an IS magazine.

Following a trial, he was found guilty of seven charges of disseminating terror documents on YouTube, WhatsApp and Telegram apps but cleared of two more similar charges and of encouraging terrorism on Twitter.

The court had heard that a number of people were killed and injured in a series of attacks on the French capital in November 2015.

The night after the atrocity, Hussain and at least one other man filmed themselves six times driving past the Victoria Barracks in Windsor, which is home to the Coldstream Guards.

In the car, they listened to Islamic chants and discussed their support for IS, the court was told.

One of the men was heard to say: "Wake up you kuffar (disbelievers), when are you gonna wake up?"

A voice on the video points out a notice outside the barracks saying it is recruiting now and adds "So are Dawla (IS)".

Later the same night, Hussain sent the video to a friend, saying: "I want to show you something."

The next day, he sent a WhatsApp message about the Paris outrage purporting to give a "Muslim perspective", jurors heard.

In June last year, he made another drive-by video around the area of Cavalry Barracks in Hounslow, where the 1st Battalion Irish Guards are based.

In a hate-filled commentary, Hussain was allegedly heard to say: "We are outside the British Barracks today, as you can see, the baby butchers of the Muslims."

The occupants of the car were heard to shout "Allah is the greatest".

When police seized Hussain's mobile phone last August, they found the black flag of IS on his screen saver and his pin number was 9117 - in apparent homage to the 9/11 and 7/7 terror attacks, the court heard.

Prosecutor Mark Paltenghi told jurors: "It may be that this is a combination of the dates of two of the most significant acts of terrorism this century - the attacks upon the Twin Towers in New York and other targets in America on September 11 2001 and part of the date of the London bombings on July 7 2005."

Hussain will be sentenced at Kingston Crown Court on September 11.
