Mahmud Ali Durrani is a Pakistani army officer. He was the National Security Advisor to Prime Minister Yousaf Raza Gillani's administration until he was fired in January 2009 for "not consulting the Prime Minister while giving statements on foreign relation matters". The matter in question was the acceptance by the Government of Pakistan of the Pakistani nationality of the sole surviving terrorist Ajmal Kasab, who was involved in the 2008 Mumbai attacks and was in the custody of the Mumbai police. Durrani had previously served as Pakistan Ambassador to the United States.
