Muktamoni drew the nation's attention with an abnormally large right arm
Muktamoni, who was diagnosed with a rare disease, has died at her home in Satkhira.
The 12-year-old died around 6:45am on Wednesday, Muktamoni's father Ibrahim Hossain told the Dhaka Tribune.
Earlier on May 20, Ibrahim said the physical condition of his daughter was critical.
Her namaz-e-janaza was held after the zuhr prayers. Later, she was buried beside her grandfather Azhar Ali’s grave.
“She has been buried at our family graveyard," Ibrahim said.
Muktamoni drew the nation's attention with an abnormally large right arm.
On August 12, 2017 doctors at DMCH removed a 3kg tumour from her arm after a biopsy showed the growth to be in the artery of her hand.
The girl later underwent three more consecutive surgeries on her right arm on August 29, September 5, and October 8, 2017.
Muktamoni's father: There was no lacking in my daughter's treatment
Muktamoni's father Ibrahim Hossain said he bears no grudges towards the doctors, or anyone, for his daughter's death.
Instead, he thanked the physicians and Prime Minister Sheikh Hasina for undertaking the responsibility of treating his 12-year-old daughter.
"Everyone tried their best for Muktamoni," Ibrahim Hossain said.
He added: "There was no lacking in her treatment. I thank the prime minister and all those who came forward to help my daughter."Breaking into tears, Ibrahim also thanked the journalists of Satkhira and Dhaka for aiding Muktamoni from his home in Kamar Basha village in the south of Satkhira Sadar upazila.
"Muktamoni stopped eating and talking since yesterday [Tuesday]," said Ibrahim. "But since she did the same thing twice before, we thought she would recover. But I did not think she would leave us."
He talked about how Muktamoni agreed to go to the Sadar Upazila Hospital for blood tests on Tuesday, and later asked to drink water in the morning on Wednesday. When Ibrahim tried to comfort her, he realized that she had stopped breathing.
Muktamoni's twin sister Hiramoni said: "I wanted to go to school with my sister. But it will never happen now, as Allah has taken her from us."
Muktamoni's mother Asma Khatun has become paralysed with grief. She only wants her daughter to call her "mother" once again.
Police Superintendent Sajjadur Rahman, representative from the office of the District Commissioner Shah Abdus Sadi, representative from the office of the Civil Surgeon medical officer Dr Farhad Jamil, and Sadar upazila Chairman Asaduzzaman Babu were present with Muktamoni's family.
Sajjadur Rahman said: "Everyone, including the prime minister, tried their best to save Muktamoni. But we failed. We will continue supporting her family."
