In the early 1970s, the army of Pakistan launched military crackdown in response to the Bangladesh independence movement. Nearly 10 million refugees fled to India. R&amp;AW was instrumental in the formation of the Bangladeshi guerilla organisation Mukti Bahini and responsible for supplying information, providing training and heavy ammunition to this organisation. It is also alleged that R&amp;AW planned and executed the 1971 Indian Airlines hijacking as a false flag operation to ban overflight by Pakistani aircraft and disrupt Pakistani troop movement in East Pakistan. Special Frontier Force, then under R&amp;AW actively participated in military operations especially in the Chittagong Hill Tracts. After the war ended in the successful creation of Bangladesh. However, four years later Sheikh Mujibur Rahman was assassinated on 15 August 1975 at his residence. R&amp;AW operatives claimed that they had advance information about Mujib-ur-Rahman's assassination but Sheikh Mujib tragically ignored inputs. He was killed along with 40 members of his family. Later, R&amp;AW successfully thwarted plans of assassinating Sheikh Hasina Wazed, daughter of Mujibur Rahman, by Islamist extremists.
