Al Queda kills Pakistani troops for the first time

There are also reports that the terrorists invited the Pakistani soldiers into a village to "negotiate" then ambushed them. Also that American operatives were involved, but no reports of any casualties.
I think the Al Queda terrorists in Pakistan just made a very big mistake. By attacking and killing Pakistani soldiers for the first time, there is sure to be a harsh response from the military, which will probably increase cooperation with American and allied forces hunting Al Queda, and crack down more seriously on elements in Pakistan sympathetic to the terrorists.
