Early in the morning, some disgruntled army officers lead the pre-planned attack to assassinate and overthrow President Bangabandhu Sheikh Mujibur Rahman. Attackers open fire indiscriminately on his residence at Dhanmondi 32.
Bangabandhu phones army chief General KM Shafiullah and says, "Shafiullah, your forces have attacked my house. Perhaps they have already killed Kamal. Send forces quickly".
Shafiullah rings his deputy General Ziaur Rahman and chiefs of two other services to mobilise troops to help the president. It is to no avail.
After killing Kamal, army officer Mohiuddin and his accomplices go around the house hunting for Bangabandhu and they find him standing calmly with his pipe in hand on the front veranda. Seeing him, even killer Mohiuddin is taken aback. He cannot shoot Bangabandhu. He merely utters, "Sir, please come with us".
As they bring him down the staircase, Bangabandhu shouts, "Where are you taking me?" At this point, Bazlul Huda asks Mohiuddin to move away and Noor opens fire at the president. Along with him, most members of his family are killed. Thus, the disgruntled army officers achieve their mission without any resistance.
Two other groups of army personnel launch simultaneous attacks on the residences of Sheikh Fazlul Haque Moni and Abdur Rab Serniabat and kill them along with their family members.
Later in the morning, Major Dalim announces on the radio, "Autocrat Sheikh Mujib has been killed".
