"Mr Nowak has not been to Guantanamo, and turned down an invitation to the camp because the US refused to give him unrestricted access to the detainees. He told the BBC that he had received reports that some hunger strikers had had thick pipes inserted through the nose and forced down into the stomach. This was allegedly done roughly, sometimes by prison guards rather than doctors. As a result, some prisoners had reported bleeding and vomiting he said. "If these allegations are true then this definitely amounts to an additional cruel treatment," Mr Nowak said."
