Two UK terror trials came to an end this week.

Al Qaeda operatives used invisible ink to write down key phone numbers. This pen was found by police during a house search

On Tuesday, a jury in London convicted Bilal Abdulla of conspiracy to murder and conspiracy to cause explosions. Abdulla was one of two people who tried to detonate car bombs in London and then, on a suicide mission, drove a jeep filled with gas canisters into Glasgow airport. His partner, Kafeel Ahmed, died in the second attack.

The trial rightly received plenty of coverage. But the case itself failed to open up much, if anything, in the way of links to Al Qaeda, or any other terrorist organisation. It was, it appears, a stand-alone operation.

Far more interesting, I think, was the result from Manchester this afternoon. For the first time in the UK, a jury convicted a man, Rangzieb Ahmed,  of directing terrorism. Not only that, they also convicted him, and his co-defendant, Habib Ahmed, no relation, of belonging to Al Qaeda.

We talk a great deal about people or plots being AQ-linked or AQ-inspired. Well here's a case, according to Greater Manchester Police head of counterterrorism, Tony Porter, that's indisputably AQ-core.

In many ways, the Manchester case was the polar opposite of the London one. It didn't have any plot or planned attack per se, but it had links to all manner of interesting people and plots. 

Here's a few:

Phone links between Rangzieb Ahmed and Yassin Omar, one of the failed London bombers.

Habib Ahmed named as a fellow traveller by Mohammed Junaid Babar, the supergrass whose testimony helped convict the fertiliser bomb plotters in May 2007.

Phone links with Abdul Rahman, who pled guilty last year to recruiting people in the UK to go and fight coalition forces in Afghanistan.

Habib Ahmed married by Omar Bakri Mohammad, founder of Al Muhajiroun, the UK's highest profile organisation supporting bin Laden ideology.

Finally, there are the links with a man at one time credited with being bin Laden's number three, Hamza Rabia.

The investigation itself included bugged conversations in Dubai, a luggage intercept at Amsterdam Schipol, and phone numbers written in invisible ink.
