UN warns that Gaza desperately needs more aid − an emergency relief expert explains why it is especially tough working in Gaza

Providing humanitarian assistance in any sudden emergency, like the one currently happening in Gaza, is complex – in terms of security, logistics and financing. Often, there are simply not enough appropriate supplies available to quickly get into an acute emergency, which might be in a remote area or might be in a restricted area, as is the case with Gaza. There are often security issues that may affect an aid group's access to a population.
