Tel Aviv, Jan 4: The UN Office for the Coordination of Humanitarian Affairs (OCHA) said that for the past three days, the world body and other partners have been unable to deliver life-saving humanitarian aid north of Wadi Gaza – the coastal wetland located along the central part of the besieged enclave. Around half of the Hamas-controlled enclave lies north of Wadi Gaza. In its latest situation update, the OCHA said the delivery of the humanitarian assistance was not possible “due to access delays and denials, as well as active conflict”. On Wednesday, the World Health Organization (WHO) had said that in the past three days, 13 trucks carrying crucial medical supplies for surgeries and anaesthesia were delivered to Gaza via the Rafah crossing.
