Bangladesh Islamist Ghulam Azam, has been reportedly found guilty on five counts of war crimes by court.
Azam, 91, was accused of setting up militia groups that carried out mass killings and rape during Bangladesh's 1971 war of independence with Pakistan, BBC reports.
According to the report, prior to the verdict, supporters of Bangladesh's main Islamist Jamaat-e-Islami party, which Azam led from 1969 until 2000, clashed with police.
According to the report, the International Crimes Tribunal found Azam guilty of five charges including conspiracy, incitement, planning, abetting and failing to prevent murder and faced more than 60 counts of crimes against humanity.
Although, Azam denied the charges and his defence lawyers are claiming none of the charges have been proved, the prosecutors are seeking for death penalty to him.
More than 100 people have been killed since January in political violence sparked by verdicts handed down by the war court, the report added.
