Syrian Observatory reports Assad used Gas to attack 'IS' fighters. (DW).

Syrian troops have gassed fighters for the "Islamic State" who were trying to capture a major airbase, a watchdog reports. Government troops and various rebel factions have long fought over the air base.

The Syrian Observatory for Human Rights announced Saturday that bombardment and gassing ended a push to take a military air base (pictured) by the "Islamic State" (IS).

IS began its offensive to capture the base, from which troops have launched air attacks - as well as a nearby barracks known as Brigade 137 - on Thursday.

Deir al-Zour lies in the northeast, between the IS-controlled province of Raqqa and the Iraqi border.

"Our brave troops managed to hit an Islamic State convoy near the Deir al-Zour military airport," Syria's state broadcaster reported Saturday, without giving further detail.

Losing Deir al-Zour would prove a major blow for Assad's regime, making it the second Syrian province after Raqqa to fall into the hands of IS, which also controls considerable swaths of territory in Iraq.

The battle for the air base and the region has killed about 70 IS fighters and 51 regime troops in the past three days, according to the Observatory, which is based in Britain and relies on reports from activists within Syria, where few unofficial media have a presence.
