WikiLeaks breach included secret details on Guantanamo prisoners

The soldier accused of the largest release of classified data in U.S. history provided WikiLeaks with secret details of prisoners held at Guantanamo Bay, threatening "serious" damage to national security, the prison's former commander testified on Monday.

Data released by Private First Class Bradley Manning included biographical material on Guantanamo prisoners, details of their religious affiliation, and names of their relatives with extremist links, Rear Admiral David Woods, who ran the Guantanamo operation in 2011 and 2012, told Manning's court martial.

Manning, 25, is in the third week of his court-martial for allegedly providing the WikiLeaks anti-secrecy website with more than 700,000 files, videos and other data, including documents from classified military databases in Iraq and Afghanistan as well as the prisoner files.
