ORIGINAL STORY: According to the Guardian, emergency services are responding to an incident of unconfirmed explosions at Ariana Grande's concert at the Manchester Arena in England.
So far we only know there were two loud bangs. One concertgoer told the Guardian “quite a loud explosion heard from inside the Manchester arena and it shook, then everyone screamed and tried to get out.” TMZ has video of fans scrambling to get out of the arena.
Sadly, it might be possible this stampede caused injuries.
