A military judge has refused to dismiss the most serious charge facing Bradley Manning, the US soldier who allegedly leaked thousands of secret documents.
Lawyers for the 25-year-old argued there is no proof he "aided the enemy", a charge carrying a life prison term.

Prosecutors have argued he "systematically harvested" documents eventually seen by Osama Bin Laden.
The case, allegedly involving 700,000 files, is considered the largest-ever leak of secret US government documents.
