Washington From graphic videos of US military assaults in Iraq and Afghanistan, to candid comments by heads of state, secrets leaked by transgender army private Chelsea Manning caused Washington major embarrassment and upset relations with its allies. In July 2010, Manning -- then a male soldier known as Bradley -- was arrested over the release of a huge trove of more than 700,000 classified military and diplomatic documents via WikiLeaks. On Wednesday, Manning was released from the prison at Fort Leavenworth in Kansas owing to a commutation of her sentence by president Barack Obama before he left office. Now 29, Manning said at the time she hoped to encourage debate about America's wars, but the leaked files stretched far beyond the battlefields in Iraq and Afghanistan, with diplomatic cables embarrassing senior officials on nearly every continent.
