The whistleblowing website WikiLeaks has begun releasing thousands of secret documents from the U.S. military prison at Guantánamo Bay, Cuba. The documents reveal the Bush and Obama administrations knowingly imprisoned more than 150 innocent men for years without charge. In dozens of cases, senior U.S. commanders were said to have concluded that there was no reason for the men to have been transferred to Guantánamo. Among the innocent prisoners were an 89-year-old Afghan villager and a 14-year-old boy who had been kidnapped. Some men were imprisoned at Guantánamo simply because they wore a certain model of Casio watches, which had been used as timers by al-Qaeda. The documents also reveal that the journalist Sami al-Hajj was held at Guantánamo for six years partly in order to be interrogated about his employer, the Al Jazeera news network. Al-Hajj’s file said he was sent to Guantánamo in order to “provide information on…the al-Jazeera news network’s training programme, telecommunications equipment, and news gathering operations in Chechnya, Kosovo and Afghanistan.”
