When the Arab Spring protests reached Bahrain, the tiny Gulf kingdom cracked down hard.
Since February 2011, when the first demonstrations started, at least 35 people have died.
Bahraini security forces have detained many more protesters.
A few have been put on trial — like the doctors and hospital nurses accused of treating wounded protesters, but refusing treatment to government supporters.
Some protesters claim they have been tortured in detention.
Human rights groups say five people have died in government custody.
