Palestinians currently have access to only 30 percent of Gaza

Palestinians currently have access to 30 percent of Gaza after Israel has restricted access to the remaining parts, according to the United Nations office for the coordination of humanitarian affairs, reported Al Jazeera on Monday.

Large areas have been declared as no-go zones, such as much of Rafah governorate, and there have been forced displacement issues in places like Gaza City. Entire regions - such as the area along the Israeli frontier - have been declared a restricted zone. 

Prior to the war, Gaza was known to be one of the most densely populated places in the world, with 2.3m people living in an area that is 25 miles by seven miles - roughly 4,000 people per square mile. With the current restrictions, people have become even more densely cramped together, making living conditions intolerable.
