Explosion at UK Ariana Grande concert.

[Atlas Has Shrugged]

I'm assuming this a freak stage accident involving props, because this seems too bizarre a target.

Link.

Edit: Sources saying multiple people dead, but a website called "Stuffz.NZ" doesn't seem credible to me. Maybe I'm just ignorant of Kiwi media. NBC has reported it on air and the term "multiple casualties" was used. Scary stuff.

Edit Edit: So Billboard is confirming multiple casualties, Fox is reporting it on air now. If this was a fireworks fiasco, Grande would have possibly been injured but she's confirmed to be unharmed.

Guardian and Telegraph both reporting multiple casualties.

[Matty]

it looks like it was a stampede. Not terror

[The Other Castro]

Oh wow, I really hope this is an accident.

[Atlas Has Shrugged]

Oh wow, I really hope this is an accident.

Me too. The thought of pre-teen girls being targeted for terror is sickening.

[The Other Castro]

Not good. I don't think a simple accident would do that.

NBC News: Law enforcement officials say at least 20 dead and hundreds have been injured following reports of an explosion in Manchester, UK.

[Phony Moderate]

Multiple witnesses seem to be saying that it's an explosion.

[Mike Thick]

Seriously, this is tragic. Bessell clan sends their best wishes across the pond.

DEATH TOLL UP TO 23

POLICE ARREST MAN IN CAR

F***ing disgusting. What pig does this.

[Phony Moderate]

Tom Newton-Dunn of The Sun has tweeted that it may be a nail bomb.

[Blair]

Honestly feel sick

[Phony Moderate]

BBC - Trains and trams have ceased running from Victoria Station.

[Matty]

Sky News reporting it's a bomb.

[Matty]

REPORTS it was a nail bomb.

This stuff needs to stop. It just does.

[Atlas Has Shrugged]

Fox hasn't mentioned a nail bomb. They've been saying that there was a bang and that it might have caused a stampede. That is almost equally terrifying.

This sucks

I doubt it was that, but it reminds me of an incident that occurred in Cincinnati before a Who concert in the 70's.

From the pics on twitter it wasn't like that at all.  This sadly definitely was a bomb. 

And British Transport Police are confirming that a blast occurred in the foyer area of the arena.

My initial hunch, due to the lack of smoke in all of the videos I've seen, was that a speaker blew. But I just spoke to my best friend (a musician with a lot of experiences with amps) and he told me that he's blown multiple speakers but has never seen one literally explode and send shrapnel.

Chris Matthews is saying it might have been a suicide bomber. The guy he is interviewing just said "then if it is a suicide bombing that means it might have been terrorism." WTF?

[Gass3268]

If this was an attack, I'm surprised that it occurred at the end of the concert, as is being reported.

[Helsinkian]

Sky News showed footage shot a quarter mile away from the arena, and even there the explosion was clearly heard. So it wasn't a small bang.

[Filuwaúrdjan]

Exactly what has happened is not clear yet, though it's clear it was very bad. Please avoid baseless speculation, please don't repeat unsubstantiated rumours.
