Pakistan initially garrisoned its troops in military bases and forts in the tribal areas until several high-profile terrorist attacks inside Pakistan and assassination attempts on Pervez Musharraf in May 2004. Musharraf ordered XII Corps and XI Corps to be stationed in Federally Administered Tribal Areas (FATA) region and take forceful action against al-Qaeda members in Pakistan's mountainous Waziristan area (in the FATA), which escalated into armed resistance by local tribesmen. March 2004 marked the beginning of the Battle of Wana in South Waziristan. It was reported that al-Qaeda's second-in-command Ayman al-Zawahiri was amongst these fighters. Pakistan responded to deploy its 10th Mountaineering Division under Major-General Noel Israel. After a week of fighting, the army suffered major casualties with hundreds of fighters being captured. However, army was unable to capture al-Zawahiri who either escaped or was not among the fighters.
