The Secretary-General continues to follow with concern the ongoing hunger strike by Palestinian prisoners in Israeli custody, in particular, those held in what is known as administrative detention.  He stresses the importance of averting any further deterioration in their condition.  He reiterates that those detained must be charged and face trial with judicial guarantees, or released without delay.  The Secretary-General urges all concerned to reach a solution without delay, and fully supports in this regard the work of his Envoy, Robert Serry, who is actively engaged on this issue with the parties on the ground.
