The three-member panel of the ICT-2 read the summary of the 154-page verdict at a jam-packed court room in the presence of a huge crowd of people, particularly journalists and lawyers, amid tightened security in and around the tribunal.
The war crimes court in June this year had framed the charges against Moinuddin and Khan.
"Ashrafuzzaman Khan is now staying in New York and Chowdhury Moinuddin is living in London," prosecutor Zeyad Al Malum had earlier told reporters.
After returning to power in January 2009, Bangldadesh Prime Minister Sheikh Hasina, the daughter of Bangladesh's independence hero Sheikh Mujibur Rahman, established the first tribunal in March 2010, almost 40 years after the 1971 fight for independence from Pakistan to castigate those who committed crimes against humanity during the nine-month war.
