It will take a little time to work out what has happened in Glagow. From eyewitness accounts, this does seem like a definite attack, but an eyewitness on BBC News 24 has just described seeing two men get out of the car and try to torch it with bottles of petrol. The BBC also have a photo plainly showing the car well ablaze on the pavement, under the canopy and pointed towards, but not having penetrated, or apparently reached, the airport doors. This would have to have been taken after the occupants got out as it is very well ablaze. This is hard to reconcile with continued journalists’ reports of the car being inside the terminal building.

Anyway, four people have been arrested, so we should get some answers on this one fairly quickly. At least two of the arrested men were Asian. There is no simple equation between Asian and Muslim but in the UK, and particularly in Glasgow, it does increase the likelihood. Fortunately, on the information so far, it seems nobody has been killed.

Thankfully, whatever is happening, we do not appear to be facing a wave of attacks by sophisticated terrorists with good bomb making skills.
