Late on December 10, ISIS terrorists attacked the headquarters of the Syrian Democratic Forces (SDF) 1st Brigade in the town of al-Busayrah in the southeastern countryside of Deir Ezzor.
During the large-scale hit-and-run attack, ISIS terrorists clashed with SDF fighters and targeted the headquarters with rocket-propelled grenades. The terrorist group’s news agency, Amaq, said that the SDF sustained “casualties” as a result of the attack, without providing any numbers.
The SDF, which is backed by the US-led coalition, is yet to comment on ISIS’ bold attack in al-Busayrah or reveal its loose.
Following the attack, the SDF closed all the entrances of al-Busayrah and imposed a curfew in the town. The group warned the locals against leaving their homes, even for work. As of December 12, the curfew is still imposed.
The US-led coalition also dispatched troops to al-Busaryah. Coalition reconnaissance aircraft were spotted over the town on December 11.

The unprecedented attack on the SDF 1st Brigade headquarters highlights ISIS growing influence in northeastern Syria. The terrorist group’s cells are now launching larger and bolder attacks than before. Meanwhile, the US-led coalition are still relying on limited security operations and raids.
