Amman, Jordan (CNN) In a patch of desert largely unseen by the outside world, a humanitarian emergency is unfolding with tens of thousands of people trying to survive in miserable conditions. Aid agencies call it "the berm" -- essentially a rocky, largely uninhabitable no-man's land on Jordan's northeastern frontier with Syria. As Jordan tightened border controls late last year and restricted access, Syrian refugees, mostly from the besieged cities of Homs and Aleppo began accumulating in a makeshift settlement in this remote region -- known as Rukban. Aid groups estimate there are more than 75,000 people, mostly women and children, stranded there now.The berm lies along Jordan's northeastern border with war-torn SyriaThe area has been closed off by the Jordanian military after an ISIS attackTens of thousands of Syrian refugees are pouring into this 'no man's land'
