Witness Tahurul Alam Molla stated in the ICT-2 on Tuesday that Subhan had stabbed his father Moazzem Hossain with a dagger in front of Iswardi Jame Mosque on Apr 17, 1971.
Later, his accomplices had knifed Moazzem to death, he added.
Tahurul had earlier testified, as the 20th prosecution witness, in the case filed against Jamaat chief Motiur Rahman Nizami for his alleged war crimes during the 1971 Liberation War.
During the Tuesday testimony, he said Nizami was also present during murder of his father.
Tahurul, 62, said his cousins Habibur Rahman and Motleb Ahmed Khan and nephew Nazmul Haq Khan had also been stabbed to death before the mosque.
The ICT-2 led by Justice Obaidul Hasan recorded his statement.
Tahurul said his elder brother Zahurul Alam had been the Ishwardi Thana committee general secretary of Bangladesh Chhatra League, Awami League’s student front, and his maternal uncle Fakir Nurul Islam the Ishwardi union Awami League president.
He knew Jamaat leaders including Khoda Boksh Khan, Nizami and Subhan for the political background of his family and relatives, he added.
The witness said an all-party council had been formed comprising leaders and activists of the Awami League and other pro-liberation forces, following Bangabandhu Sheikh Mujibur Rahman’s call for independence on Mar 7, 1971.
Pakistani army and their local accomplices Jamaat and Nizam-e-Islami Party attacked Pabna district police lines on Mar 26, he said. They had moved towards Ishwardi amid resistance by police and ordinary people.
Tahurul said the Pakistani troops and their local collaborators had taken shelter at Goplapur Sugar Mill where they had killed many officers and employees, including its manager ‘Azim’.
He said they had carried out a massacre in Ishwardi on Apr 12, when his father, uncle Habibur, cousin ‘Motaleb’ and nephew Nazmul Haq Khan Helal had taken shelter in Ishwardi Jame Mosque.
According to the statement, Tahurul started for Ishwardi along with his friend ‘Fantu’ to take his father and other relatives to Tilakpur.
Tahurul said he had come to know from an old man near his aunt’s house beside the mosque that people were being killed under the leadership of Khoda Boksh and at the instruction of Subhan and Nizami at a torture cell near the mosque.
“The old man said that Kholda Boksh and his accomplices killed my uncle Habibur Rahman at the instruction of Subhan Moulana and Motiur Rahman Nizami, taking him out of the mosque. Hearing that, we refrained from going to the mosque and came to Tilakpur.”
He said he had again gone to Ishwardi and reached near the torture cell beside the mosque on Apr 17.
“I saw a white car in front of the house. I also saw Moulana Subhan and Motiur Rahman Nizami entering the house from the car.”
Tahurul said after a while Subhan and Nizami had entered the mosque for saying their prayers.
“The prayers over, they came out of the mosque and stood in front of the house. Later, my father was dragged from the mosque to a ditch-like place near the coal depot beside the mosque,” he added.
Now weeping, Tahurul continued: “Moulana Subhan also went there. Motiur Rahman Nizami was standing there. As soon as Subhan stabbed my father taking a dagger from another man, he groaned saying Allahu Akbar (Allah is great).”
“Later Subhan’s accomplices kept stabbing my father and at one stage he died.”
The witness said he had gone to the place to bring his father’s body on Apr 18, when he had seen his cousin Motaleb and nephew Nazmul being killed the same way.
Tahurul identified Subhan during the testimony.
He said he had already given statement to the investigation officer.
Following the completion of the testimony, defence lawyer Mizanul Islam started cross-examining him.
Later, the tribunal adjourned the hearing until Wednesday.
Earlier on Dec 31 last year, the ICT-1 framed charges against Subhan.
The nine charges against him include murder, genocide, abduction, torturing, looting, arson and conspiracy.
The charge-sheet against Subhan was submitted on Sept 15.
On Oct 19, the ICT-1 took cognisance and ordered a hearing on the charges.
Born in 1936, at Toilokundi village of Pabna's Sujanagar Upazila, Subhan was the chief of Pabna unit of Jamaat-e-Islami and a member of the party's highest policymaking body during the post-liberation war era.
During the Liberation War, he was the General Secretary and subsequently the Vice-President of 'Peace Committee' in Pabna.
The Jamaat leader was arrested in Tangail, east of Bangabandhu bridge, on Sept 20 last year.
