British prosecutors say they will not charge British officials or spies over the detention and rendition of two opponents of the late Libyan leader Moammar Gadhafi.

Abdel Hakim Belhaj and Sami al-Saadi allege the British government and its MI6 intelligence agency colluded with American authorities in their kidnappings and ill-treatment.

The men were detained with their families in southeast Asia in 2004 and sent to Gadhafi's Libya, where they were imprisoned. They accused former Foreign Secretary Jack Straw and an ex-senior MI6 officer Mark Allen of responsibility.

The British government denies complicity in rendition or torture.

Police asked prosecutors to consider charges against one suspect, who has not been named. Sue Hemming of the Crown Prosecution Service said Thursday there was "insufficient evidence to charge the suspect with any criminal offense."
