Attacks increase every spring.
That was what I was going to say. Isn’t it as regular as clockwork there (in Afghanistan) that the violence goes up in the spring each year?
Right, but the article also points out that the amount has been going up on a year-to-year basis too:
2005 - 400 attacks
2006 - 800
2007 - 1,000
That more than a 200% increase every year.
