The US army soldier is serving a 35-year prison term for passing classified files to WikiLeaks
US Army soldier Chelsea Manning, who is serving 35 years of jail term for passing classified files to WikiLeaks, was sent to 14 days in solitary confinement on Friday for attempting suicide and keeping a banned book.
A group supporting Manning released a statement saying that a disciplinary board at the military prison in Kanas informed her of the decision after a hearing on Thursday.
According to Reuters, Manning was quoted in the statement saying she could appeal the punishment.
"I am feeling hurt. I am feeling lonely. I am embarrassed by the decision. I don't know how to explain it," Manning said.
In the statement, Manning also said the prohibited book in her prison cell was "Hacker, Hoaxer, Whistleblower, Spy" by Gabriella Coleman.
Army spokesman Wayne Hall told Reuters in an email that "it would be inappropriate for the Army to comment at this time".
A lawyer for Manning, Chase Strangio of the American Civil Liberties Union, questioned the logic of "our systems of incarceration punishing people with the cruelty of solitary for attempting to end their life", Reuters reported.
Manning, a 28-year-old transgender Army private, had sparked a worldwide debate on government secrecy after she provided more than 700,000 documents, videos, diplomatic cables and battlefield accounts to the anti-secrecy group WikiLeaks.
Manning was born male and revealed after being convicted of espionage that she identifies as a woman. She tried to commit suicide in July.
This month, she also went on a hunger strike, agreeing to end it when the Army said she would be allowed to receive gender transition surgery, following which she began hormone therapy in 2015.
