'Jihadvertising': Charity adverts run with jihad videos

Adverts for charities, government organisations and the BBC are running on video sharing websites before some jihadi videos, Newsnight has found.
Jihadi videos from ISIS and other terror groups have become prime tools for radicalising young Muslims.
The system by which adverts are allocated to videos is often automated but means that those uploading the videos could earn money from the adverts.
