Maybe we can finally cross “poverty” off the list of root causes.

Sky Crime Reporter Martin Brunt said two of the men arrested, one at Glasgow airport and one on the M6, are believed to be hospital doctors working in the UK.

He said: “This is very far removed from the picture we normally have. These are professional people with highly paid jobs who are intent on killing people.”

Meanwhile a suspect car has been blown up by police in the grounds of the Royal Alexandra Hospital in Paisley where one of the suspects from the Glasgow airport attack is in a critical condition and being held under armed guard.

The hospital was cordoned off and army disposal experts called in to carry out the controlled explosion. Strathclyde Police said they believed the car was connected to the attack at Glasgow airport but did not contain explosives.

Why blow up a car if it doesn’t contain explosives?

UPDATE at 7/1/07 3:26:25 pm:

More info at the Daily Mail: Two doctors held over bomb attacks.

One of the doctors, the man arrested on the M6, was said to be a Jordanian-born doctor at the North Staffordshire Hospital in Stoke-on-Trent.

He lived with his wife and baby in a rented house in Newcastle-under-Lyme, Staffordshire, where forensic officers were carrying out a detailed search last night.

The doctor is suspected of having played a key role in the planning of the terror strikes.

One of the two men overpowered as they attacked Glasgow Airport has 90 per cent burns and is too badly injured to be interviewed, but the second was being questioned last night.

Police believe they are all part of a previously unknown Al Qaeda-linked cell made up of people of Middle Eastern origin.

The doctor involved in the Glasgow attack is an Iraqi who is thought to have been granted asylum in the UK while a third suspect comes from Lebanon.

At least one other member of the cell was still being hunted last night.
