BBC Verify has authenticated footage circulating online which appears to show the moment police opened fire on a man at the Manchester Synagogue.
In the clip - which appears to have been taken by a passerby - two armed officers can be seen standing pointing their weapons at a figure lying prone on the ground.
As the camera pans, a different person is seen lying at the gate to the synagogue surrounded by a pool of blood and a black car stopped immediately to his right.
One of the officers then approaches the fence, where a small group of people had gathered, and shouts: "Everybody else, he has a bomb. Go away."
Seconds later the figure being watched by police appears to attempt to stand up. Sharp cracks ring out and the man falls to the ground.
