People across the country are observing the National Mourning Day on Sunday, the darkest chapter in the history of independent Bangladesh. Prime minister Sheikh Hasina paid rich tributes to Father of the Nation Bangabandhu Sheikh Mujibur Rahman, marking the 46th anniversary of his martyrdom and the National Mourning Day on Sunday. The prime minister paid homage to the Architect of the Independence by placing wreaths at his portrait in front of Bangabandhu Memorial Museum at Dhanmondi Road No 32. After placing wreaths, the prime minister stood in solemn silence there for some time showing respect to the great leader and the great architect of Bangladesh’s independence. A smartly turned out contingent of Bangladesh Armed Forces gave a state salute, while bugle played the tune of grief and somber to the last post.
