The Babrra massacre occurred on 12 August 1948 in the Charsadda District of the North-West Frontier Province (now Khyber Pukhtunkhwa) of Pakistan, when unarmed workers of the Khudai Khidmatgar movement were fired upon by the provincial government on the orders of the then Chief Minister Khan Abdul Qayyum Khan. The protest was against the promulgation of Public Safety Ordinance by the provincial governor and the resulting arrests of Khudai Khidmatgar leaders and confiscations of properties. Different sources state different numbers of people killed in this massacre (some as large as 600). And even larger numbers were injured.
