It isn't known yet if he died or not, this morning on the news they didn't say anything about it yet. Yesterday they only knew that he was transported to a specialized hospital to treat his wounds.
But most of the times they won't tell you whether someone survived a suicide attempt, even if it was performed so publicly, out of respect for the family and the victim itself.
lol, this guy set himself on fire.. in front of everyone, it was on the news, I think they'll let us know ;)
