Syrian media reported that the local army conducted a massive strike to the positions of ISIS in Deir ez Zor. This is reported, in particular, by Sana Syrian state news agency.
It is reported that air and artillery strikes were carried out against ISIS headquarters, and as a result of the attack more than 70 Islamic State fighters were killed. Also news agency reported on the destruction of military equipment, in particular a tank and an armored personnel carrier.
We recall that the western outskirts of the city is the easternmost territory of Syria, and it is controlled by government forces. As of early 2017, the Syrian airbase in Deir ez Zor was under the control of the Syrian Arab Army. In December 2016, the number of the government servicemen in the blocked areas of Deir ez Zor was estimated at 4,000 - this is the regular army, police units, and militia units.
