The Daesh are using three methods, to confront the attacks carried out by the U.S.-backed Syrian Democratic Forces (SDF), in the eastern province of Deir al-Zour.
The Daesh militants, in the eastern countryside of Deir al-Zour, are using tunnels, to move underground, between positions and front-line, to avert being targeted, said the Syrian Observatory for Human Rights.
The militants are also relying on counter-attacks against the SDF, which has recently started a broad offensive, backed by the U.S.-led coalition, against the Daesh pockets on the eastern bank of the Euphrates River.
The third method, the observatory continued, is depending on an extensive network of mines, planted around the Daesh-held areas, to prevent the SDF from storming in.
The Britain-based watchdog group said, 38 SDF fighters and 57 militants were killed, since the battle against Daesh-held pocket started on Sept 10. It said, the SDF militias are advancing in the fight, in the al-Baghous area, near the Syrian-Iraqi border, in the eastern countryside of Deir al-Zour.
The SDF are also advancing in the town of Hajin, another area in the Daesh-held pocket. The battles are coupled with intensive air strikes by the U.S.-led coalition, according to the observatory.
Recent reports said, the Daesh control over Syrian territory has shrunk to one percent, after it captured almost half of the country, a couple of years ago. The Syrian army stripped the Daesh of large swathes of areas in Deir al-Zour, including the provincial capital, while the SDF is attempting to consolidate positions, in the northern and north-eastern countryside of Deir al-Zour.
