CIA ‘held Gadaffi torture victim on British soil’

Monday 14th April 2014

Kidnapped Libyan politician Abdelhakim Belhadj held briefly in overseas territory Diego Garcia

Fresh evidence emerged yesterday that the CIA held a Libyan opposition leader on British soil before delivering him to Gadaffi torturers.

Kidnapped Libyan politician Abdelhakim Belhadj alleged that he was told by Gadaffi’s own spy chief that the plane which delivered him to Libya had stopped at the British overseas territory of Diego Garcia.

Mr Belhadj, who was kidnapped along with his pregnant wife as they boarded a flight in Malaysia in 2004, made the claim through his lawyers, provided by human rights charity Reprieve.

He said: “The first time I heard that I had gone through a place called Diego Garcia was when I was told by the head of the Libyan intelligence, Moussa Kousa, during my first interrogation session in a prison outside Tripoli.

“He was running the interrogation, and was angry that it had taken a long time for me to arrive in Libya.

“I told him that the plane had stopped somewhere on the way from Bangkok.
“He told me that he knew, and that the plane had landed on an island in the Indian Ocean called Diego Garcia.”

The claim is supported by a CIA flight plan discovered in 2011 at the offices of Gadaffi’s head of intelligence Moussa Kousa showing the joint CIA-MI6 operation had been scheduled to stop at Diego Garcia.

Reprieve deputy director Polly Rossdale said the revelations pile pressure on Tory Foreign Secretary William Hague to answer the allegations.

“The government must come clean about the UK’s role in this dirty affair,” she said.

If that jet had crashed into the sea, some trace of it would have been found by now.

Surely if a plane that size hits the water it will break up and leave some clues on the surface? I cannot believe that nothing has been seen or found.

If, just if. when the plane came down, the sea was as calm as a lilly pond **. If the plane was brought down to a perfect emergency landing, similar to the plane that landed in the Hudson River a couple of years back.
If the plane didn't breakup on landing. Is it possible for the plane to sink to the bottom without a trace?

** I have sailed across the Atlantic many time, often going via the "Sargasso sea".
For those who don't know. The Sargasso Sea is in the area of the "Bermuda triangle" the water is as calm as a lilly pond.

I'm unsure if there is an area in the Indian Ocean similar to the Sargasso sea.
