Gonojagoron Moncho is set to lead a procession from Shahbagh to Home Ministry on Thursday, demanding justice for publisher Faisal Arefin Dipan.
Moncho spokesman Imran H Sarker made the announcement Tuesday.
The procession will be brought out around 11am.The pro-liberation youth platform will also stage a protest rally in the capital around 3pm Friday, demanding the arrest of Dipan's killers.
Earlier in the day, the anti-war criminals platform observed a half-day countrywide hartal without any major incident.
Moncho activists blockaded the capital's Shahbagh intersection as they protested the killings and attacks on secular bloggers and publishers.
Sources said two minibuses vandalised in the morning in Shahbagh. However, there was no other reports of violence during the hartal. Traffic movement did not see any disruption in the city.
On Saturday, Dipan – who published books by slain writer-blogger Avijit Roy – was hacked to death inside his Jagriti Prokashoni office at the capital's Aziz Supermarket.
Only hours earlier, Ahmedur Rashid Tutul, another one of Avijit's publishers, along with a blogger and a poet were also attacked by unidentified assailants in Lalmatia.
