More accounts have emerged of torture and abuse at the US military’s Bagram prison in Afghanistan. BBC News says it’s collected testimony from nine witnesses describing human rights violations at a secret Bagram jail in the period since President Obama took office. One prisoner said the secret facility is known as the "Black Hole." Prisoners reported being subjected to sleep deprivation, freezing temperatures and other abuses. One prisoner said he lost half a row of teeth after a US soldier struck him with the butt of a gun. The same prisoner also recounted being forced to dance to music every time he wanted to use the toilet.
