Pakistan - Al-Qaeda HQ based there

That's according to captured Zarqawi documents. The BBC reports.

A letter found when al-Qaeda's chief in Iraq was killed said the group's leadership was based in Waziristan, Pakistan, the Washington Post reports.

The December 2005 missive is said to be the first to emerge from what the US military calls a "treasure trove" after Abu Musab al-Zarqawi's death in June.
