As reports flooded social media Monday night of at least 19 fatalities and nearly 50 injured after an explosion following an Ariana Grande concert at Manchester Arena, those same platforms were also being used to unite parents with children separated during the tragic moment, as well as reveal the immediate aftermath in horrifying photos and videos snapped on smartphones.

Videos show concertgoers in Manchester, England, rushing out of the stadium in a scene of chaos and confusion, with countless people on their cellphones while hurriedly looking around for friends and family. Police had flocked to the scene by the time hundreds of audience members were fleeing, their vehicles' blue lights illuminating the outside of the arena.

Still images of a video from within the concert seemed to show people running, though it wasn't clear whether some were rushing into the stadium or toward the exits. A witness reportedly told The Guardian some people may have been running back into the concert during the panic.
