Polish Prime Minister Kazimierz Marcinkiewicz says he is ordering an investigation into reports that the CIA had run secret prisons for suspected terrorists in Poland.
Mr. Marcinkiewicz told Polish television, TVN 24, the matter must finally be closed because it could prove dangerous for Poland.
Polish authorities have repeatedly denied reports that Poland was the main European center for detaining such suspects.
Meanwhile, Germany's Foreign Minister Frank-Walter Steinmeier denied suggestions that his country's security officers played any role in the detention of a German citizen by CIA agents. Mr. Stainmeier told the newspaper Bild such reports are irresponsible.
He was referring to the case of Khaled el-Masri, who was mistakenly abducted by American agents in Macedonia in 2003 and held for five months in Afghanistan.
