Iran's interior minister has suggested that up to 225 people were killed in November protests sparked by a petrol price hike, ISNA news agency reported on Sunday.
Officials in Iran have yet to issue an overall death toll for the unrest, while London-based human rights group Amnesty International has put the number at more than 300.
The protests erupted on November 15 in Tehran and rapidly spread to at least 40 cities and towns, with petrol pumps torched, police stations attacked and shops looted, before being put down by security forces amid a near-total internet blackout.
Officials had repeatedly denied death tolls given by foreign media and human rights groups as "lies", and passed responsibility of reporting on it between different state bodies.
"Sad things happened. About 40 or 45 people, meaning around 20 percent of those killed, were shot with non-standard issue weapons and martyred," said Interior Minister Abdolreza Rahmani Fazli.
"No armed confrontation with the people happened... but when they attack a police station, they have to be confronted," ISNA quoted him as saying.
His breakdown indicated that, according to the government, between 200 and 225 people were killed in the violence.
According to Amnesty, at least 304 men, women and children were killed during the unrest.
Iran has blamed the violence that broke out during the protests on "thugs" backed by its foes the United States, Israel and Saudi Arabia.
It has singled out exiled royalists and the People's Mujahedeen of Iran (MEK), an exiled former rebel group which it considers a "terrorist" cult.
The minister said the petrol price hike had been "just an excuse" for creating chaos as foes had wanted a "civil war" in Iran.
He also defended the internet blackout, saying that the MEK, monarchists, and the Islamic State group were "giving military training through the internet".
