UK spies to be investigated over claims they were complicit in torture of CIA prisoner

Investigatory powers tribunal to examine complaint brought by Mustafa al-Hawsawi, who was tortured while detained by CIA

The UK's intelligence agencies are facing a rare judicial investigation after a tribunal said it would look into allegations that British spies were complicit in the torture of a prisoner held by the CIA.

The investigatory powers tribunal (IPT) said late last week it would examine a complaint brought by Mustafa al-Hawsawi, a Saudi citizen who was tortured between 2003 and 2006 while detained in a network of secret CIA prisons.
