The armed conflict began in 2004 when tensions, rooted in the Pakistan Army's search forAl-Qaeda fighters in Pakistan's mountainous Waziristan area (in the Federally Administered Tribal Areas), escalated into armed resistance. Pakistan's actions were presented as its contribution to the international War on Terror. Clashes erupted between Pakistani army troops and Arab and Central Asian militia forces. The foreign militants were joined by Pakistani non-military veterans of the War in Afghanistan which subsequently established the Tehrik-i-Taliban Pakistan and other militia organizations such as Lashkar-e-Islam. The Tehreek-e-Nafaz-e-Shariat-e-Mohammadi (TSNM) established in 1992 allied with the Tehrik-i-Taliban Pakistan and Lashkar-e-Islam.
