Some of the desperate attempts being made by migrants to enter the UK have been caught on camera.

The images show men running towards trucks at Calais and climbing on to the vehicles before sitting on the axles.

The images are from a BBC investigation which shows how British trucks are being targeted just metres from the Calais port entrance.
