Prime Minister Sheikh Hasina yesterday asked people not to forget the terrible days of the arson violence unleashed by "BNP-Jamaat" in the name of movement.

"I would like to ask people of the country to be alert so that none can resort to such incidents anymore in future," she said.

The premier was addressing an event titled "Cries of Arson Violence: A partial scenario of BNP-Jamaat Fire Terrorism, Anarchy and Violation of Human Rights" organised by Awami League at National Museum Auditorium in the capital.

She said some 500 people were burnt to death and more than 3,500 people were injured during the "arson violence of BNP-Jamaat" in 2013-15.

"We tried our best to stand beside the victims and took steps for their treatments. But it is not possible to wipe out the pains and sufferings of the people who lost their dear ones," she added.

"I just would like to tell the people of the country that none should forget that awful time," she said.

The PM said if anyone wants to do politics, they can do healthy politics. "We don't have any objection (with healthy politics). But if anyone attacks my people, they (attackers) will not be spared. It (violence) can't be tolerated. No one can endure it," she said.
