Black Lives Matters protesters have blocked the motorway route into Heathrow Airport.

Protesters unveiled a giant banner saying "This is a Crisis" and laid down in the middle of the road on Friday morning.

The protest could affect thousands of holidaymakers making their way to the airport.

Channel 4 News' Symeon Brown filmed footage of the tailbacks.

A Metropolitan Police spokesperson told ITV News that officers were at the scene and dealing with the incident.
