The US military has released details of its case against David Hicks, an Australian held without trial at Guantanamo Bay for five years.
David Hicks has been at Guantanamo Bay for five years
Mr Hicks is facing charges of providing material support for terrorism and attempted murder.
He was captured in Afghanistan, where he allegedly fought alongside the ruling Taleban against US-led forces.
His continued imprisonment is causing problems for the Australian government, which has faced calls for his release.
The document released by the Pentagon on Friday sets out its case against Mr Hicks in detail.
It alleges that he took part in an al-Qaeda training course in 2001, and spent weeks learning about covert photography, the use of dead drops and wearing disguises.
It also claims that Mr Hicks used the alias Abu Muslim Australia as he conducted surveillance of the American and British embassies in Kabul.
Many Australians are angry that Hicks is still at Guantanamo
During that time, it is alleged he drew diagrams of the buildings, windows and doors, and documented the people coming and going.
The Pentagon has claimed before that he travelled to Kandahar airport, and was issued with an AK47 rifle to defend it against American-led forces.
Now US officials say that he also managed to arm himself with 300 rounds of ammunition and three grenades.
The timing of these new details may well have a political dimension, because US Vice-President Dick Cheney arrives in Australia next week.
The case of David Hicks is hanging over the visit.
The Howard government is under pressure, even from its own back benches, to secure a date for the Australian inmate's trial.
Former Liberal Party Prime Minister Malcolm Fraser has also accused the government of betraying the basic legal rights of its citizens, and claims that Mr Hicks will never get a fair trial.
