“Officials: There will be a controlled explosion opposite the library within one minute as part of bomb squad activities.”-Boston Globe
Turns out that media source Boston Globe had reported that bomb drill(?) was taking place in Boston on the day of the Boston Marathon, which seems to be a bad time to hold a drill.
Two explosions hit the finish line of the Boston Marathon, then a third explosion hit the JFK library (which was mentioned in the bomb drill announcement). Some reports are now saying the library explosion was caused by an electrical problem?
Tweet left on Boston Globe website said the library was on fire, before explosion occurred.
