Prime Minister Sheikh Hasina and her younger sister Sheikh Rehana on Saturday laid the foundation of 'Mujib Pathagar' (library) at 32 Dhanmandi in the city. Speaking on the occasion the prime minister said that the library being built by Bangabandhu Memorial Trust will help the younger generation know true history of Bangladesh and the supreme role played by the father of the nation in achieving the country's independence in 1971.  She said that the nation was deprived of knowing the true history on Bangladesh and Bangabandhu Sheikh Mujibur Rahman for many years after his assassination in 1975.

"It won't be possible now as the new generation is aware of true history," she said. Briefing reporters Prime Minister’s Deputy Press Secretary K M Shakhawat Moon said Hasina and Rehana, daughters of Bangabandu, offered munajat on the occasion. The premier recalled that the anti-liberation forces had promulgated an indemnity ordinance to prevent the trial of Bangabandhu's killers in 1975.  Back to power in 1996 the Awami League government revoked the black ordinance paving the way for  holding the trial of the killers and relieving the nation of years of stigma.    Also read: PM urges US companies to boost investment in Bangladesh  Hasina said her only goal has been to build  a happy and prosperous “Sonar Bangla” and bring smiles on the faces of the people as dreamt by Bangabandhu.
