Humanitarian corridor
A humanitarian corridor is a type of temporary demilitarized zone intended to allow the safe transit of humanitarian aid in, and/or refugees out of a crisis region.  Such a corridor can also be associated with a no-fly zone or no-drive zone. 

Various types of "humanitarian corridors" have been proposed in the post–Cold War era, put forward either by one or more of the warring parties, or by the international community in the case of a humanitarian intervention. Humanitarian corridors were used frequently during the Syrian Civil War.

United Nations Safe Areas

United Nations Safe Areas (UN Safe Areas) were humanitarian corridors established in 1993 in the territory of Bosnia and Herzegovina during the Bosnian War by several resolutions of the United Nations Security Council.
