Pakistan Condemns Bombing

This article maybe proof to what I've written below, that air strikes aren't always successful, and can bring a new set of problems:

Pakistan on Saturday condemned a purported CIA airstrike on a border village that officials said unsuccessfully targeted al-Qaida's second-in-command, and said it was protesting to the U.S. Embassy over the attack that killed at least 17 people.
Thousands of local tribesmen, chanting "God is Great," demonstrated against the attack, claiming the victims were local villagers without terrorist links and had never hosted Ayman al-Zawahri.
Two senior Pakistani officials told The Associated Press that the CIA acted on incorrect information in launching the attack early Friday in the northwestern village of Damadola, near the Afghan border.
