Jason Rezaian, a Washington Post journalist imprisoned in Iran, has been kept in a prison cell for the past 141 days without a mattress, forcing him to sleep on the floor, according to his family. Rezaian has untreated back pain from sleeping on concrete, chronic eye infections that may leave permanent damage, and a groin inflammation that has left him unable to stand on occasion. Iran still has not explained why he was arrested or when he may be tried. Rezaian’s family is also worried about his psychological state, saying he has been kept in near-total isolation. “Never has a Western journalist been held this long. It’s taking a devastating toll on him, physically and mentally,” said his brother Ali.
