One of the worst mass shootings in US history claimed 49 lives at Pulse, a gay nightclub in Orlando, Florida, on June 12, 2016.
The shooting occurred on the venue's Latin Night, and many of those killed were Latino.
The gunman was killed by police after a three-hour standoff, while people trapped inside desperately called and messaged friends and family.
It was the deadliest mass shooting in the United States until one year later, when 58 people were murdered at a Las Vegas country music concert.
