Brazil has declared three days of national mourning for 231 people killed in Kiss nightclub fire in the southern city of Santa Maria.
The fire reportedly started after a member of a band playing at the Kiss nightclub lit a flare on stage.
Authorities say most of the victims were students who died of smoke inhalation. The first funerals are expected on Monday morning.
It is the deadliest fire in Brazil in five decades.
Brazil postponed a ceremony due on Monday in the capital, Brasilia, to mark 500 days to the 2014 football World Cup. In Santa Maria, 30 days of mourning were declared.
President Dilma Rousseff, who cut short a visit to Chile, has been visiting survivors at the city’s Caridade hospital along with government ministers.
“It is a tragedy for all of us,” she said.
Authorities have released the names of the victims, after revising down the death toll from 245.
More than 100 people were being treated in hospital, mostly for smoke inhalation.
Officials will now investigate reports that a flare was lit on stage, igniting foam insulation material on the ceiling and releasing toxic smoke.
They will also look at claims that many of those who died were unable to escape as only one emergency exit was available.
The fire broke out as students from the city’s federal university (UFSM) were holding a freshers’ ball, the Diario de Santa Maria, a local newspaper, reported.
A local journalist, Marcelo Gonzatto, said the flare had “started a huge and fast fire that grew quickly and made a very dark and heavy smoke.”
“Lots of people couldn’t get out and died mainly because of the smoke not the fire,” he said.
Witnesses spoke of scenes of panic after the fire started, and a stampede as people tried to escape.
One, Mattheus Bortolotto, told local television: “It was sheer horror. The emergency exits did not work, and then I lost my friend in the confusion. Then a girl died in my arms. I felt her heart stop beating.”
A large number of victims were trapped in the club’s toilets, they said, possibly after mistaking them for an exit.
Survivors and police inspector Marcelo Arigony said security guards briefly tried to block people from leaving the club, the Associated Press news agency reported. Bars in Brazil commonly make customers pay their whole tab at the end of an evening before they are allowed to leave.
One of the owners of the club is reported to have confirmed that they were in the process of renewing its license to operate, and that its fire safety certificate had expired last year.
He is said to have received threats on the internet – in addition to surviving members of the band that was performing on stage when the blaze started.
Its guitarist, Rodrigo Martins, told local radio: “It might have happened because of the Sputnik, the machine we use to create a luminous effect with sparks.
“It’s harmless; we never had any trouble with it. When the fire started, a guard passed us a fire extinguisher. The singer tried to use it but it wasn’t working.”
He said the band’s accordion player had died in the fire.
Brazilian broadcaster Globo said most of the victims were aged between 16 and 20.
A temporary morgue was set up in a local gym as the city’s main morgue was unable to cope.
Family members came to identify the dead, led in one by one to see the bodies, Diario de Santa Maria reported.
