Photos: The Las Vegas shooting from the perspective of survivors and first responders

A gunman fired into a country music festival in Las Vegas, Nevada, last night, killing more than 50 and injuring hundreds. The suspect, identified by police as 64-year-old Stephen Paddock, opened fire from the window of a room at the Mandalay Bay Resort, which overlooked the Route 91 music festival.

Video and pictures from the scene show confusion and terror at the indiscriminate attack, and the tense hours of emergency organizing and rescue that followed.
