The spy balloon was shot down in Qandil strait region after it was picked up on the Syrian army's radar system.
In mid-July, the Syrian military forces shot down two spy drones of the ISIL terrorist group flying over their positions in Deir Ezzur's districts.
The two unmanned aerial vehicles (UAV) were brought down after they were intercepted over government forces' positions in the neighborhoods of al-Sina'ah and al-Jabaliyeh.
The ISIL's drones were equipped with imaging devices.
Last Monday, the Syrian army's air-defense units opened fire at a US Air Force reconnaissance drone over the al-Thardah mountain in the Southern countryside of Deir Ezzur.
"The Syrian army troops fired several times at the US drone in al-Thardah mountains, forcing it to leave the region immediately," FNA reported.
