Tragedy at Brazil Nightclub, at least 245 dead: I love fireworks, but using them indoors is almost always a bad idea...

Just before the fire broke out...
just like Rhode Island

Victim receiving first aid outside the Kiss Club in Santa Maria, Rio Grande do Sol, Brazil

This is just a horrible story.  

The cause of the fire is not yet known, however, some media reports claim the blaze was ignited by a firework set off inside the club during the band's performance.
Local newspaper Diario de Santa Maria reported that the fire started at around 2am.

Club security guard, Rodrigo Moura, is quoted in the paper as saying the venue was at maximum capacity of between 1,000 and 2,000. He said partygoers were pushing and shoving to escape.
Ezekiel Corte Real, 23, was quoted by the paper as saying he helped people to escape. 'I just got out because I'm very strong,' he said.

Factually it appears similar to the Rhode Island club fire which killed 96 back in 2003.

This is a story that happened just a few hours ago.  So expect better reports as time passes.  RIP to those who died.
