UN chief Antonio Guterres said Sunday he was "shocked by harrowing levels of death, injury and destruction" in north Gaza, where Israeli forces are carrying out attacks they say aim to prevent Hamas regrouping. "The Secretary-General is shocked by the harrowing levels of death, injury and destruction in the north, with civilians trapped under rubble, the sick and wounded going without life-saving health care, and families lacking food and shelter." bgs/dw
