According to various information sources, terrorists are lacking food and water as result of the recent military operation, which destroyed most of their supplies.
The airstrikes affected basic food supply chains of the fighters, ammunition and medical supplies, RIA Novosti reported, citing representative of Syria’s military intelligence.

According to him, militants are experiencing serious difficulties with food and drinking water. In some terrorist units, the food will run out in less than a week, the source said.
He quoted imprisoned terrorists who reported that a “critical” situation for ISIL “has evolved with the medicines necessary to treat the wounded and injured fighters.”
“The shortage of medicines and medical supplies forced the militants to leave the wounded to the care of the local people. Moreover, in order to hide from the Russian aviation, fighters had to get rid of large trucks with material supplies, which slowed down the retreat of the forces,” he added.
