As was alluded to by our colleagues, the camp system actually goes back to the Stalin era and the Soviet Union's pioneer camps.
In the case of Crimea, one facility, Artek, was built by Stalin. In the case of other facilities such as those in Moscow, they're often referred to as family centres. There are some that are thematic in nature. One is a music camp. There is a computer science camp. They differ based on age groups, and the conditions differ as well.
The fact is that we have only 300 kids back and that gives us a very minimal base of evidence right now to understand the conditions inside the camps. All we have as the primary base of evidence on conditions in the camps are the statements of the Russians themselves and the photos and videos they release on websites. We need to have access for the International Committee of the Red Cross and UN access to be able to figure out exactly how these kids are being held. We don't know.
