This is a more or less typical incident; there have been many others like it. It illustrates how jihadist violence, although it is perpetrated by people who think they are saving their lands, actually destroys those lands: this man was "with a firm providing security for a road project." The end result of this violence will likely be that the road won't get built. But at least the land will be purified of infidels.
From the BBC, with thanks to Sr. Soph:
A British man has been kidnapped in Afghanistan after the convoy he was travelling in was attacked.
The man was with a firm providing security for a road project.
At least three policemen are believed dead after the ambush in the west of the country. The party's interpreter was also reportedly abducted.
The Briton's abandoned vehicle has now been found, and Nato-led troops are using checkpoints and a surveillance aircraft in their search for the men.
There is confusion over who was responsible, with the Taleban blamed by police and security officials while a government spokesman initially blamed criminals.
Taleban spokesman Abdul Latif Hakimi told the Pakistan-based Afghan Islamic Press that they were behind the attack.
