At a rally in front of the National Museum at Shahbagh on Tuesday, they demanded a judicial inquiry into the attacks to prevent a recurrence of such incidents.
People from all across the social spectrum joined the protest and condemned the attacks.
At least 100 people were injured, 50 houses and 17 temples belonging to the Hindu community were vandalised, with some burned down, at Nasirnagar on Oct 30 over a Facebook post defaming Islam allegedly by a Hindu fisherman.
Theatre activist Ramendu Majumdar said the recent chain of attacks tarnished Bangladesh's image as a secular country.
“Attacks on Nasirnagar would not have taken place if exemplary punishment was meted out for such previous attacks on the minorities, including that in Ramu,” he said.
About Nasirnagar attack, Ramendu said: “Whether MP Sayedul Haque influenced it or not, he should resign. The government should also figure out internal clashes in the ruling party and set example by a judicial probe.”
Police have detained 53 men over the Nasirnagar attacks. The ruling Awami League has suspended three of its Nasirnagar unit leaders for their involvement in the incidents.
Sharafat Hussain, one of the organisers of the event, said: "We are truly sorry that the persecution of the minorities is occurring across the country.
“As the residents of Brahmanbaria, we are ashamed. This event has been organised to demand punishment of the actual criminals who are behind the incidents.”
