Two students were sentenced to death on Thursday by a Bangladeshi court for the murder of a prominent atheist writer and blogger, Ahmed Rajib Haider, in Dhaka in 2013.
Six others were handed down prison sentences for their role in the killing of Haider.
Haider was hacked to death after returning home from a public rally demanding the execution of Islamist leaders who committed war crimes during the 1971 conflict two years ago.
Police, at the time of the murder, reported that Haider was hacked by two machete wielding assailants striking him in the head, jaw and shoulder before his throat was slit.
Five Bangladeshi atheist writers and bloggers in 2015 were murdered for speaking out against Islamic extremism.
