London: Saudi King Abdullah Bin Abdul Aziz, in talks with US officials, floated the idea of implanting electronic chips in former Guantanamo Bay inmates to track them after release, the Guardian newspaper reported on Wednesday.
The newspaper said US officials heard the proposal from King Abdullah at his palace in March this year.
In a discussion with White House counter-terrorism adviser John Brennan about how to deal with detainees, King Abdullah interjected: "I've just thought of something."
According to the cables, the king proposed "implanting detainees with an electronic chip containing information about them and allowing their movements to be tracked with Bluetooth. This was done with horses and falcons."
Brennan replied: "Horses don't have good lawyers". He said such a proposal would face legal hurdles in the United States but he would look into it, the newspaper reported.
In Riyadh on Tuesday, an unnamed Saudi foreign ministry official told state media that Saudi Arabia would not comment on the US diplomatic cables issued by WikiLeaks as it was unsure about their reliability.
