A Guantanamo Bay prisoner has died of what the Pentagon is calling an “apparent suicide.” The prisoner, Muhammad Ahmad Abdallah Salih, was thirty-one years old. A Yemeni national, he had been held at Guantanamo without charge since 2002. He had previously taken part in a long-running hunger strike that had left him weighing as little as around eighty-six pounds. It’s the fourth apparent suicide by a Guantanamo prisoner.
