SHAKER AAMER fears that he will never be released from Guantanamo Bay — despite the Obama administration setting his date of freedom for Sunday.

The last British detainee in the US military prison in Cuba added yesterday that he was not getting his hopes up as he had been promised release before.

The Obama administration had to give Congress 30 days’ notice on September 25 of Mr Aamer’s release. He has languished in Guantanamo without charge or trial for nearly 14 years.

Mr Aamer sent a letter to the BBC through lawyers to say: “I will believe it when I get [to Britain].

“They told me eight years ago that I was cleared to leave, and here I am, still here.”

Save Shaker Aamer Campaign chairwoman Joy Hurcombe told the Star: “The failure to give Shaker and his family firm assurance that he will be released this time is shameful but consistent with the utter cruelty that has been shown to them.

“Their ordeal continues until Shaker is safely home. We will be on the streets until then.”

The campaigners will urge the US to keep its promise by holding a protest vigil tomorrow outside Downing Street from 2pm.

Campaigners say the reluctance to release him is down to his accounts of torture at Guantanamo such as US guards using force-feeding and humiliation.

At least 315 people so far — including activists, MPs and celebrities — have pledged 24-hour fluid-only fasts to encourage Mr Aamer, 46, to drop his hunger strike.

Ms Hurcombe, who was fasting yesterday, said: “There should be a plane on the runway at Guantanamo ready to bring him home tomorrow, but I rather doubt that it’s there.”

The father-of-four, who has never met his youngest son as he was born on the same day Mr Aamer was captured in Afghanistan and sold to US forces, cried when he heard about the campaigns in Britain.

“All of you people have helped me to feel that I am not all alone. I hope that some time I will be able to pay my respects to you all,” he said.
