United Nations aid chief Martin Griffiths said on Monday during a trip to Aleppo, Syria, that the rescue phase in response to the earthquakes that hit Syria and Turkey was "coming to a close," and that urgency must now switch to providing shelter, food, schooling and psychosocial care. He said the UN would have aid moving from government-held regions to rebel-held northwest, a front line across which aid has seldom passed during the Syrian conflict.
