WARSAW, May 21 (Xinhua) -- Polish Prime Minister Jaroslaw Kaczynski said on Monday that Poland considered the CIA prison issue closed, the PAP news agency reported.

    The UN Committee Against Torture on Monday appealed that it needed additional information on Poland's inquiries into the matter "despite Poland's earlier assurances that no CIA cells were located on its territory."

    "This will allow us to close the case," the committee said.

    Charges that Poland and Romania housed CIA detention centers for terrorists first appeared in the media in 2005. Both countries denied the existence of such cells on their territory.

    Inspections by a special European Parliament commission found no proof of their existence in Poland, PAP reported.
