Denmark to investigate alleged CIA flights

COPENHAGEN — Denmark will investigate claims that the CIA secretly used an airport on the Nordic country's remote Arctic territory of Greenland to transport prisoners in the Bush administration's war on terrorism, the Danish prime minister said Thursday.

Denmark began investigating reports in 2005 that the CIA had quietly touched down on its territory as part of the agency's "extraordinary rendition" program.

Human rights groups have criticized the American practice, in which suspects are transported for interrogation to countries outside the United States, some of which allow torture.

A documentary broadcast Wednesday by the DR1 TV network reported that flights had touched down in Greenland.
