It's being gradually confirmed that devices were responsible for these explosions. AP reports that an intelligence chief has stated that two more devices are being dismantled and there has been a controlled explosion on a potential third.

I think it's safe to say now that it's an act of terrorism, but from who is still too early to say.

A graphic showing the approximate location of the explosions:

There has been reports of an explosion at the Library, possibly the controlled explosion from earlier. It's getting a bit confused now, but Boston PD are said to be doing a statement soon so that will hopefully clear things up a bit.

Third explosion at the JFK library. No further details yet.

Wouldn't call it amateur hour, looked like two perfectly timed explosions by remote, probably low grade powder by the white smoke. Just hope this is the end.

Police officials have said there has been a 3rd explosion at the JFK Library, but no info on casualties.

23 injured reported. Hopefully not many more die from this.

That number sounds very conservative on CNN they say 46 people injured several critically.Sounds about right judging from some aerial shots of the area they are showing now lots of what looks like blood.Whoever planted the bombs they wanted to kill the crowds that would be standing near the finish line.

I hope that they did a sweep of the area if someone was really nasty they would plant more devices to explode a few hours after the first ones.

Being British and old enough to have experienced a few of these, it's definitely terrorist, its probably domestic (the target isn't high enough profile to be otherwise) and it's too sophisticated for your average pissed off hormonal high schooler,

News media outlets are going bonkers about now. They'll probably call it the Boston Massacre.:hmmm:

I'd say we're all too far away and uninvolved to speculate right now. I'm Irish, border counties, and also old enough to know what this looks like. But I can wait to hear from those on the scene.

No one can say for sure yet who is behind the attack.I am never a fan of speculation.I recall the attack in Norway a few years back every was crying "Islamic extremist" and that was wrong.The target is as viable for an Islamic extremist as it could be for a any other terrorist.The Boston Marathon is an international event after all.

That being said the fact that a bomb was placed near a library implies someone with a more political agenda.

I agree, let's let the authorities have a chance to complete their investigation. :yep:

Domestic terrorist is entirely possible. Timothy Mcvay anyone? We do have our fair share of extremist groups. Whoever is responsible, it's a reasonable assumption that they had a fairly good idea on what they were doing . The event, location, placement, and timing of the explosive's are telling to the intent and forethought that has gone into this.

That said, i saw a Blaze article saying some saudi national was under guard, but i think that's just tabloid conjecture BS.

Possible device at Tufts Medical Centre. Some reports say EOD team inbound, some say there's been another explosion

Rgr that :yep:

I know one thing, if they find the person(s) behind this, and if they aren't middle eastern in decent, this WILL be politicized in the worst way. Hell, that already started on page one of this thread, and other places on the web.
