Syrian Army Advance in Deir Al-Zour

Added On September 11, 2017

A Syrian military source said the army captured the Tharda Mountains in eastern Syria's Deir al-Zour province on Sunday.

The operation was the first step towards securing  the Deir al-Zour airbase,  as the mountains function as its first line of defence.

Deir al-Zour was a key stronghold for IS and is of strategic importance due to its proximity to Iraq.

The Syrian army and allied troops broke the IS siege on the airbase on Saturday, just a week after lifting the IS' three-year siege on Deir al-Zour in eastern Syria.

An anonymous source said the U.S. had bombed Syrian troops in the Tharda Mountains in September 2016, killing 90 soldiers.
The U.S. strike led to IS control over the mountains in 2016.

The source added IS had suffered serious losses following the advance of the Syrian forces in the area.

The progress comes as Syrian army on Sunday seized full control of the main road from the capital Damascus to Deir al-Zour city in eastern Syria, stripping the IS of key areas along the road.
