20 dead, hundreds injured
the explosion occurred at the end of an Ariana Grande concert (insert "wow that concert must've been the bomb xd" here)
people were leaving at the time and while the explosion did a lot of damage the majority of the injuries were caused by the horrified stampede as they ran for their lives
victims are thought to be teenage girls, as would be at an Ariana Grande concert
perpetrator is thought to be a Self Delete bomber, no allegiance or motive yet (but really take a loving guess)
Manchester and the surrounding area have both had a long history with terrorist attacks and with thwarting terrorist attacks
