Since its defeat in Tora Bora, Afghanistan, in late 2001, thousands of al-Qaeda-linked militants have been regrouping in the Pakistani tribal region of Waziristan (see December 2001-Spring 2002). The Pakistani army finally entered Waziristan in May 2002 (see Late May 2002), but the army remains in the administrative capital of Wana, leaving al-Qaeda free to operate in the countryside. Emboldened, al-Qaeda begins setting up small mobile training camps in South Waziristan by August 2002. [Rashid, 2008, pp. 148]
