Deir EzZor has been the site of recent ISIS attempts to take over the city from government control. The city is an enclave of government held territory in eastern Syria surrounded by ISIS and within reach of its defecto capital of Raqqa.
The Syrian Arab Army under the leadership of General Zahreddine has successfully repulsed all advances by the terrorist group into the city.
However, aid is scarce because it’s under siege from the ISIS. The video shows one operation of Russian jets providing aid to the city.
