The national is set to observe the 'Genocide Day' on Sunday, commemorating the brutalities carried out by the Pakistani occupation forces on the unarmed Bangalees on the night of 25 March in 1971.
The day will be observed officially for the second time in the country as parliament unanimously adopted a resolution on 11 March, 2017 to observe 25 March as the Genocide Day.

Besides, the government has decided to observe a one-minute 'blackout' programme at 9:00pm on Sunday on the occasion.
On the night of 25 March 25 in 1971, the Pakistani military junta resorted to mass killing in Dhaka to implement their blueprint to thwart the Awami League's assumption of office following the election mandate of 1970.
In the attack dubbed 'Operation Searchlight', the Pakistani forces mercilessly killed the Bangalee members of the East Pakistan Rifles and police, students, teachers and common people.
They killed people indiscriminately, set fire to houses and property, and looted business establishments, leaving a trail of destruction.
Meanwhile, president Abdul Hamid and prime minister Sheikh Hasina issued separate messages on the occasion.
In his message, the president said the 25th March mass killing is a black chapter not only in Bangladesh but also in the history of the world humanity.
"The mass killing carried out by the Pakistani army on the soil of Bengal was the most barbaric genocide in the 20th century," he said.
With deep respect, the president recalled father of the nation Bangabandhu Sheikh Mujibur Rahman as Bangladesh got independence through a nine-month armed freedom war under his leadership. Abdul Hamid also remembered the 25th March martyrs, four national leaders and freedom fighters.
Noting that the terrible killings committed by the Pakistani occupation forces and their local agents is a stigmatised chapter, the president said Bangladesh has been able to remove the stigma to some extent through the trial of those who had been involved in crimes against humanity during the liberation war.
Hamid urged all, irrespective of their views, creed and caste, to join the journey of establishing a non-communal and democratic Bangladesh being imbued with the spirit of the liberation war and democratic values by firmly upholding the spirit and ideologies of Bangabandhu.
In her message, prime minister Sheikh Hasina said Pakistani forces and their local agents Razakar, Al-Badr and Al-Shams members carried out the cruel carnage across the country and killed some three million people in the nine months following the dark night.
There is no example of killing so many people in such a short time, she said.
Hasina said Bangabandhu declared the independence of Bangladesh just before he was arrested in the early hours of 26 March. The declaration was spread throughout the country through the erstwhile EPR wireless and teleprinters and telegraph.
Responding to the call of Bangabandhu, the Bengalee nation earned the final victory on 16 December, 1971 through a nine-month bloody liberation war.
The prime minister said the 1971 genocide carried out in Bangladesh is one of the most terrible ones in the world.
On the democracy killing day, she pays tributes to Greatest Bangalee of all time and father of nation Bangabandhu Sheikh Mujibur Rahman and recalled the four national leaders.
