The trial has begun of an American soldier accused of providing thousands of secret documents to the WikiLeaks website. In its opening statement, the prosecution said Private Bradley Manning dumped classified documents onto the internet and into enemy hands.
Prosecutors are trying to prove Manning helped the enemy, which carries a potential life sentence. Manning says he did not believe the information would harm the US.
