'This is Vegas': Heartwarming photos of queues of people lining up to donate blood following Las Vegas mass shooting

Tragedy has the upside of bringing out the best in people.

The Las Vegas massacre, the deadliest mass shooting in modern US history, has led dozens of people to queue up to donate blood to the victims.

Police have confirmed that 59 people have died and there are more than 515 people injured.

The lines for blood donation wrap around some blocks and extend down entire streets, as people respond to calls to help shooting victims.
