The World Health Organization has been unable to get a desperately needed medical aid convoy through to civilians in the rebel-held part of Aleppo despite a government promise last month to give it access. The non-governmental Union of Syrian Medical Relief Organisations, made up of Syrian doctors, says cholera, typhoid, scabies and tuberculosis are spreading among the 360,000 people in rebel-held Aleppo for lack of treatments or vaccines. The area is cut off on three sides by the Syrian army. All sides in Syria's three-year civil war have prevented medical supplies crossing front lines, fearing they could be used to help wounded enemy fighters.
