Calling on the panel of judges to prevent such moves by the accused, Nice said that in his testimony for the prosecution two years ago Ashdown had explained the circumstances in which the recording was made when he visited Kosovo in his capacity as an envoy of British Prime Minister Tony Blair.
Milosevic dismissed Nice's claims, saying that the recording spoke for itself about Ashdown's role.
Judge Patrick Robinson warned Milosevic that he would not tolerate such behaviour in the future.
Nice said Milosevic had put together two separate recordings, one of which showed Ashdown inspecting an automatic rifle held by two uniformed KLA soldiers, and the other showing him in a house holding rifles and grenades brought to him by Albanian civilians.
Nice recalled that according to Ashdown's explanation, the civilians were showing him the weapons they were forced to buy from Serbian forces so that they could hand them over to the police when demanded to do so.
The recording showed Ashdown promising his help and saying to the Albanians that he would inform PM Blair of what he had seen in Kosovo and that it was scandalous that the international community had not done anything.
