The counterproductive part is that while the bomber (gender apparently still in contention, no ID that I've seen anywhere) took out several of the intended targets, the chosen place for this event was...a World Food Programme event. The words coming to my mind go something like "I mean, honestly" but that doesn't seem right. It just seems, again, counterproductive--there was no other way to do this? Of course intimidation is a major part of coercing the local populace in any insurgency effort, but this sort of thing is not too far off from what lost al-Qaeda a lot of support elsewhere.
At any rate, 43 people were killed in this incident, and:
On Friday, a force of 150 militants in Mohmand Agency (just south of Bajaur), had targeted 5 checkpoints of the Frontier Corps, a Pakistani government paramilitary unit, killing 11 troops in the Safi and Baizai districts. Some 24 of the rebels were killed in a riposte by government sources. This attack also came in revenge for the Taliban having been expelled [by the Salarzai] from those areas of Mohmand Agency.
On Saturday, Pakistani troops using helicopter gunships came back after the insurgents, allegedly killing 40 of them in Baizai and Lakro villages.
This leaves the headline at "Over 80 Dead."
Juan Cole has a pretty good roundup of what all went down.
If only Four Lions were all there was to it.
