Attack reminds us to be vigilant
The investigation into the attempted terror attack in Stockholm at the weekend is still in its early stages, but there are some tentative conclusions that can be drawn.
The first is that the attack was incompetent. The car bomb had similarities with previous failed attempted attacks in New York, Glasgow and London. And the individual found dead in the area had been carrying an explosive device, which would seem to suggest that this was the bomber himself.
But the incompetence of the execution allows no complacency. Although just two people were hurt (other than the presumed bomber), this could easily have been lethal. Six years after the Madrid train bombings, the threat of terror still haunts Europe's streets.
