More and more Israel is denying or restricting the flow of humanitarian aid into Gaza, according to the United Nations, Al Jazeera reports.

In the second half of January, “humanitarian partners continue to observe an increasing trend in denied and restricted access to the northern and central areas of Gaza”, said the UN’s Office for the Coordination of Humanitarian Affairs.

It cited excessive delays for aid convoys before or at Israeli checkpoints and heightened military attacks in central Gaza.

“Threats to the safety of humanitarian personnel and sites are also frequent, not only impeding the delivery of time-sensitive and life-saving aid, but also posing serious risks to those involved in humanitarian efforts.”
