CIA chief backs torture

The director of the US Central Intelligence Agency, General Michael Hayden, has defended the methods it uses to interrogate terror suspects.

Gen Hayden said programmes such as extraordinary rendition produced what he said was irreplaceable intelligence.

Under the programme, terror suspects are transported to secret prisons in countries with less stringent interrogation rules.

Mr Hayden, speaking in Chicago, said the leads gained justified rendition.

"The irreplaceable nature of that intelligence is the sole reason why we have what I admit freely is a very controversial programme." Link
