Prime Minister Sheikh Hasina on Sunday paid rich tributes to August 15 martyrs at the Banani Graveyard in Dhaka.
The premier along with her younger sister, Sheikh Rehana, went there in the morning and paid glowing homage by placing wreaths.
Afterwards, they stood in solemn silence for some time.
They also spread flower petals on the graves.
Sheikh Hasina and Sheikh Rehana also silently recited Surah Fatiha and prayed for eternal peace for the departed souls of the martyrs of August 15.
Their mother, Bangamata Begum Fazilatun Nesa Mujib, brothers Sheikh Kamal, Sheikh Jamal and Sheikh Russel, and other martyrs of August 15, 1975 were laid to rest at the Banani Graveyard.
Bangabandhu, Begum Fazilatun Nesa Mujib, their three sons Sheikh Kamal, Sheikh Jamal and Sheikh Russel, most of their family members, and his three close relatives were assassinated on August 15, 1975 by a group of disgruntled army men.
Two daughters of Bangabandhu, Prime Minister Sheikh Hasina and Sheikh Rehana, could escape the carnage as they were abroad at the time.
