www.msnbc.msn.com/id/10842035/U.S. officials told NBC News on Friday that American airstrikes in Pakistan overnight Thursday were aimed at the No. 2 man in the al-Qaida terror organization — Ayman al-Zawahri.
One official said intelligence indicated a strong possibility that Zawahri was in the Pakistani village at the time of the airstrike, but there is no confirmation that he was killed.
Pakistani officials say U.S. aircraft, apparently CIA Predator drones, fired as many as 10 missiles at the residential compound.

Reports indicate as many as 30 villagers, including some women and children, were killed.
The attack came in the Bajur region of Northwest Pakistan, along the Afghanistan border.
The CIA Predators carry as many as four Hellfire missiles. Only last month, the CIA used a Predator to kill the No. 3 man in al-Qaida in a similar Hellfire strike in Pakistan.

Who is Ayman al-Zawahri?
Killing Zawahri would be a major psychological victory for the United States in its war on terrorism. Zawahri, not Osama bin Laden, has emerged recently as the chief operator for al-Qaida.
While some remains were reportedly recovered from the site of the attack, there was still no confirmation Friday night that Zawahri was among the dead. An intelligence official told NBC that it does have a sample of Zawahri's DNA.
“Anyone who tells you there is clarity on whether he [Zawahri] was killed ... do not take what they are saying as gospel,” a senior U.S. official said.
