Palestinian mourners carry the body of Arafat Jaradat, a Palestinian prisoner who was killed in Israeli prison upon his arrival to the al-Ahly hospital in the West Bank city of Hebron, on February 23, 2013. The cause of Jaradat's death is disputed. The prison claims that the 30-year-old father of two died of a heart attack, while Palestinian activists claim he was killed during questioning.
