The men stand accused of murder, abduction, torture and looting during the 1971 Liberation War in the five charges levelled by the prosecution.
The accused are former Islami Bank director Sharif Ahmmed alias Sharif Hossain, Md Ashraf Hossain, Md Abdul Mannan, Md Abdul Bari, 'Harun', Md Abul Hashem, advocate Md Shamsul Haq alias 'Badar Bhai', and SM Yusuf Ali.
All of them, except Haq and Ali, are absconding.
Police brought the two to the tribunal on Monday morning for the verdict delivery.
Shahbagh police OC Abu Bakar Siddique said that the men were transported from the Kashimpur prison in Gazipur to Dhaka.
The two are now kept in the tribunal's lock-up after the prison van carrying them reached the court premises around 9am, the tribunal's Registrar Shahidul Alam told bdnews24.com.
The trial began in October last year after the tribunal indicted the eight accused, five months after the prosecution levelled charges against them.
