Case not closed

"We closed the issue in December and we will not go back to it," Marcinkiewicz said, but added: "If legislators from Brussels come, they will be received with hospitality."

Human Rights Watch has said it has circumstantial evidence indicating that the CIA transported suspected terrorists captured in Afghanistan to Poland and Romania. Both countries have denied the claims, and Poland closed its December investigation without releasing any findings.

Two weeks ago the EU parliament decided to launch an investigation into the matter, while a separate inquiry is also being conducted by the Council of Europe, the continent's leading human-rights watchdog. (Reuters)
