In a new development in the growing uproar over alleged CIA secret prisons in Europe, the Guardian of London says it has obtained flight logs showing more than 300 CIA flights have landed at European airports. The Washington Post recently reported the CIA has been operating secret prisons in former Soviet states in Eastern Europe. At the request of the Pentagon, the Post did not name the countries. The disclosure prompted the European Union Justice Commissioner to threaten sanctions against any member state found to have hosted a secret CIA prison. According to the Guardian, CIA planes visited both Germany and Britain over 80 times. On Wednesday, the State Department announced it will respond shortly to European requests for an explanation on the alleged prisons.
