Where Guantanamo's hunger strike began
It is the longest hunger strike in Guantanamo's history, with more than 100 detainees now refusing food.
Thirty-six people are currently being tube fed and five have been hospitalised as part of a protest against conditions in the prison.
President Obama faces continuing pressure to close down the jail and make arrangements for the 86 detainees, who have been cleared for release.
The BBC's Jonathan Beale has been given a tour of the facility's "Camp Five" where the strike began.
