The Syrian Democratic Forces (SDF) announced Sunday the launch of a wide-scale security operation aimed at bolstering its region in the eastern regions, commencing from Deir Ezzor amid a general state of alert in the city of al-Hasakah, following reports of an uprising by ISIS terrorists in the south of the city.

The US-backed SDF has put its forces on high alert and deployed patrols in most neighborhoods of al-Hasakah while checking the ID cards of pedestrians. They indicated that the "alert is concentrated around the Ghuweiran neighborhood and Industrial Secondary School prisons in the south," sources familiar with the matter told Al Mayadeen.

SDF "informed the owners of businesses in the neighborhoods under its control that they had to shutter their shops within an hour. It is expected that a general curfew will be declared in the city of al-Hasakah," they added.

"ISIS detainees in the Industrial Secondary School prison might be engaging in an insurrection, with no information about any of the elements managing to escape," the sources said.

In 2022, ISIS carried out an attack on the Industrial Secondary School prison, during which more than 800 members managed to escape from the prison after detonating a car and a motorcycle at the entrance of the prison.

Later in the year, Al Mayadeen sources reported that the Raqqa Central Prison was attacked and that scores, maybe hundreds of prisoners, including ISIS members, had escaped.

The sources added that the Syrian Democratic Forces (SDF) armed groups cordoned off the perimeter of the prison and deployed patrols throughout the city while bringing in large military reinforcements.

ISIS terrorists detained in prisons controlled by the US-backed SDF have since 2021 been engaging in riots and civil disobedience.

SDF took over two weeks to restore security in the prison and the neighborhoods of Ghuweiran, Az-Zuhur, Al-Layliyah, Al-Nashwa, and Al-Nashwa Al-Gharbiyyah, most of whose residents were forced to flee due to the clashes that took place between the two sides and the airstrikes by the international coalition.

Reliable sources reported to Al Mayadeen in June that 25 ISIS terrorists detained in a prison belonging to the so-called "military police" of the Turkish-backed militant groups in the city of Ras Al-Ain, north of al-Hasakah Governorate, managed to escape from the prison at dawn on Friday.

The sources indicated that the number of those who managed to escape are one Saudi, one Kuwaiti, 11 Iraqis, and 13 Syrians, adding that their whereabouts remain unknown, amid expectations of their success in reaching the city of Ceylanpinar, adjacent to Ras Al-Ain.

Violent clashes between the Syrian Democratic Forces (SDF) forces and ISIS members took place in the northern dormitories inside Al-Sinaa Prison, south of the city of al-Hasakah earlier.

Our correspondent added that the warplanes of the US-led International Coalition carried out several raids in the vicinity of the prison.

That came despite the SDF announcing the complete seizure of Al-Sinaa prison in the Syrian al-Hasakah Governorate.
