The jury trying the case of an alleged Islamic extremist accused of planning a Lee Rigby-style terror attack against British or American soldiers on UK military bases has been sent home for the day and is due to resume deliberations at 10am on Wednesday.

Delivery driver Junead Khan, 25, is said to have used his job to drive close by East Anglian air bases, including RAF Lakenheath and RAF Mildenhall, which host US Air Force (USAF) units.

After his arrest in July, al Qaida instructions for making a 'viable' pipe bomb and pictures of a large military-style knife he had searched for on Amazon were found on his laptop at his Luton home, the court heard.

Khan is charged alone with making preparations for attacking military personnel in the UK between May 10 and July 14 last year, which he denies.

He is on trial at Kingston Crown Court alongside his uncle, Shazib Khan, 23, also from Luton, with whom he is jointly charged with making preparations for travelling to Syria to fight for Islamic State (IS).

The pair deny engaging in conduct in preparation of terrorist acts between August 1 2014 and July 15 2015.

Sending jurors out after the Easter break, Mr Justice Edis asked them to put aside recent events involving IS and the terror attacks in Belgium, which took place on the day they first retired.

He said: 'We have all heard a lot about ISIS (another term for IS) since you were last in this building. Just remember that whatever it is that has happened, and whosever fault it is, it wasn't their (the defendants') fault.

'They were not involved in any of that, and your job is to return now and think about the evidence in this case, and not be affected by by any other thoughts.'

The prosecution claim that Junead Khan planned to travel to Syria with his relative but altered his plan to focus on an attack in the UK, either on British or US service personnel.

The court has heard documents found on Junead's computer showed he researched buying items including a combat knife on Amazon.

He claims that while he supports the establishment of an Islamic State, he does not wish to become a fighter himself.

Shazib Khan admits exchanging messages with friends saying they had a 'role to play' and that he wanted to help 'by any means', but insisted he meant through providing money and food, not violence.
