The FBI has released new footage showing the suspect in the killing of US activist Charlie Kirk running across a roof – from where the fatal shot was fired – before dropping to the ground and crossing a road.

As the authorities continue their search, BBC Verify’s Nick Beake has been looking at the footage and what we know about his escape.
