KANSAS (REUTERS) - Chelsea Manning, seen here as Bradley Manning, was hospitalised on Monday (July 4), according to her attorney.

The US soldier reportedly tried to commit suicide, while imprisoned for handing over classified files to WikiLeaks.

The Army confirmed 28-year-old Manning, who was born male but identifies as a woman, has been released back into custody from the hospital.

There are no reports available of Manning's current medical condition.

Manning is serving a 35-year sentence after a 2013 military court conviction of providing more than 700,000 documents, videos, diplomatic cables and battlefield accounts to WikiLeaks.

It was the biggest breach of classified materials in US history.
