US President Barack Obama's decision Thursday to shut secret CIA-run prisons abroad brought renewed calls for their locations to be disclosed as well a fresh denial from Poland, one of two eastern European countries most closely linked to the practice. Across Europe, governments uneasy that CIA flights had been carrying terrorism suspects through their airports and air space for years said they were relieved to be heading into a new rendition-free era. Dick Marty, the Swiss lawmaker who spearheaded the Council of Europe investigations that sought to expose the existence of clandestine interrogation centers in Eastern Europe and Africa, said he expected the truth would come trickling out once the centers were closed. "For some countries, things are going to become very embarrassing. I think European countries would do well now to tell the truth," Marty said in an interview with The Associated Press.
