(Reuters) - Soldier Chelsea Manning, who is serving 35 years in a military prison for leaking classified documents to WikiLeaks, was found guilty on Tuesday of violating jail rules and given three weeks of recreation curbs, the American Civil Liberties Union said.

The former intelligence analyst was convicted in 2013 of providing more than 700,000 documents, videos, diplomatic cables and battlefield accounts to WikiLeaks, in the biggest breach of classified materials in U.S. history.
