What Hamas does to their people when they try getting humanitarian aid in Gaza?

While Israel is making great efforts to ensure the entry of aid is being facilitated to the people of Gaza, Hamas continues to steal and hide it from Gazan civilians.

In this video, you can see masked individuals, that according to Gazan civilians are Hamas members, beating and holding civilians captive after they attempted to enter a warehouse where humanitarian aid was stored. These civilians just wanted to eat, but Hamas had other plans.
