Baizai (Urdu: {{Nastaliq| بائزئی ) is an area of Upper Mohmand Tehsil, Mohmand Agency in the Federally Administered Tribal Areas of Pakistan.[4] [5] [6] The area's local population consists entirely of Pashtuns, with many residents belonging to the Bazai sub-tribe of the larger Pashtun Mohmand tribe. In November 2011, the area came under media headlines when US-led NATO forces attacked a Pakistani military checkpoint in the town of Salala located in Baizai, killing 26 soldiers.[7]
