“Shaker Aamer claims that the US authorities are systematically making the regime more hardline to try to defuse the strike, which now involves almost two-thirds of the detainees. Techniques include making cells ‘freezing cold’ to accentuate the discomfort of those on hunger strike and the introduction of ‘metal-tipped’ feeding tubes, which Aamer said were forced into inmates’ stomachs twice a day and caused detainees to vomit over themselves. The momentum behind efforts to release Aamer – who has spent more than 11 years without trial inside the camp – mounted sharply last week with David Cameron raising the issue directly with Barack Obama.”
