Chilling stories of survivors are emerging following the death of 19 people in a suspected terror attack at an Ariana Grande concert in Manchester, in northern England.
Thousands of people, including many young girls, were gathered to hear the US pop singer perform at Manchester Arena, which has a capacity of 21,000 people. Just as Ariana Grande was leaving the stage, a huge explosion shook the arena.
You can find more details about the suspected terror attack and the response effort here, but here's a snapshot of the horrific events, as we understand them so far.
Here's the moment the blast went off, captured on camera:
Following the initial sounds of the blast, some security personnel report the "loud bang" was merely some of the hundreds of pink balloons bursting, or sound equipment breaking.
Nevertheless, panic mounts inside the packed stadium as concert-goers rush screaming to the exits, forming a crush as they try to leave:
At 10:33pm (7:33am AEST), emergency services receive reports of an explosion at the arena. Police cars and ambulances race to the scene:
Concert-goers begin pouring out of the stadium. In the confusion, families and friends are separated.
Calls start going out on social media for missing loved ones.
Paramedics and other emergency services treat the injured at the scene.
Over the course of the evening, 59 people are taken to six hospital across Greater Manchester, while many others are treated at the scene.
There are unconfirmed reports of shrapnel wounds.
Meanwhile, police work on securing the area -- getting everyone out, cordoning off surrounding streets and locating any other potential explosive devices.
Chief Constable Ian Hopkins of the Greater Manchester Police says "We are currently treating this as a terrorist incident until we know otherwise."
