Israel denies about 50% of humanitarian operations
The Israeli military has imposed increasingly unpredictable and restrictive time windows for humanitarian movements through the two checkpoints between the south and north of the Strip.
As an example, he cited that on August 24, a protective barrier at the checkpoint, supposedly broken, caused a mission to be blocked for four hours. The repair of the barrier resulted in the non-delivery of 10,000 vaccines, 58 loads of medicines, including cold chain items and vital medical supplies for pregnant women, as well as 24,000 liters of fuel.
The UN agency also exposed the sad cases of two crucial operations to save the lives of families with children trapped under the rubble. The first mission, in the town of Hamad, was hindered by Israeli forces for three consecutive days, despite initial indications that there were survivors, including children. The second mission, in Rafah, was similarly hampered. “When rescue teams were finally allowed to reach the scene, no survivors were found,” the Office noted. Likewise, a subsequent operation in Rafah aimed at recovering the remains of 30 people to give them a dignified burial was denied, he added.
The violence faced by humanitarian workers at checkpoints is another of the serious concerns of the UN Office, which recalled the multiple incidents of shooting at humanitarian convoys when they approached checkpoints, despite that the vehicles were clearly marked and had received prior confirmation from Israeli forces.
