The British newspaper the Daily Telegraph has released pictures from inside some of Egypt's high security prisons.
The leaked videos show how prisoners are being held in conditions, which are, according to rights' groups, illegal even under Egyptian law.
Since the overthrow of President Mohamed Morsi in July, rights groups estimate that up to 21,000 people have been detained across the country.
