The freed health workers speak:
Valentina Siropulo, 48, nurse:
"I confessed during torture with electricity. They put small wires on my toes and on my thumbs. Sometimes they put one on my thumb and another on either my tongue, neck or ear
"The only thing that kept me alive during all these years - the painful, terrible tortures, the uncertainty, the death sentences - was the belief I cherished in my heart, in my soul, that we are innocent."
Kristiana Valcheva, 48, nurse:
"I was tortured with electric shocks, beaten and submitted to every kind of torture known since the Middle Ages.
"What kept me going was the fact that I am innocent and that I believe that if there is no human justice, there is God's justice and it will come some day.
"In the coming days I will try to learn how to be free. Thank God it is over. I hope to start my life anew."
Snezhana Dimitrova, 54, nurse:
"The good thing was that I never understood a word of what they were accusing us of in court, never accepted that they were talking about me.
"I want to forget the horror we lived through, I do not want to talk about it, I even spared my family the details about what we really went through.
"I left there a country with a vicious problem. I regret that I was chosen as one of the scapegoats for solving it. Maybe there was no other way."
Ashraf Juma Hajuj, Palestinian doctor granted Bulgarian citizenship:
"I thank great Bulgaria ... I am happy that all this ended well. Hope dies last."
