"The launches of Kalibr cruise missiles ensured the advance of the Syrian government forces, as well as thwarted plans of ISIS militants in the area of Deir ez-Zor."

The Syrian army supported by the Russian Aerospace Forces has been advancing toward Deir ez-Zor from three directions as part of the campaign to free the city launched in August.

The Russian Defense Ministry announced on Monday that the Syrian government forces had driven ISIS terrorists out of key positions on the Palmyra-Deir ez-Zor highway.

Deir ez-Zor, located on the shores of the Euphrates River to the northeast of Damascus, and a military airfield near the city have been besieged by ISIS for over three years, with food and ammunition only being delivered by air, while helicopters from the city of Qamishli have been evacuating the wounded and delivering essential supplies to the city's population.

The lifting of the siege of Deir ez-Zor will lead to the complete defeat of the most combat-effective formations of the ISIS terrorist group in Syria, the chief of the Russian General Staff's Main Operational Directorate said earlier.
