The situation in Idlib right now is beyond catastrophic if the Russian/Syrian offensive continues. The Syrian Regime and it’s Russian allies have bombed and begun launching a large-scale military attack on the Idlib Province in northwest Syria. Rumors have circulated that chemical weapons will be used in the attack, causing even more displacement. 50,000 people have already been displaced from southern Idlib, Jisr Alshugoor and north Hama (Latamneh). Tents that accommodate 5 people now have 10 and these new IDPs will likely never go back to their villages and cities.
There is nowhere for displaced people to go beyond Idlib except the Euphrates shield area and Olive Branch to the north east that is controlled by Turkey (which cannot accommodate a large displacement). Turkey has sealed its border and is not allowing refugees in. Turkey already has 3.5 million Syrian refugees and there is an expected 1-2 million more Syrians who will be displaced at the Syrian-Turkish border. This number is biblical and the worst in the history of the Syrian crisis and probably in the recent history of humanity. Preparations are underway in Turkey to accommodate 580,000 IDPs (with about 100,000 tents) in Efrin/Euphrates shield area, though nothing is finalized.
