Third Day of Deadly Fighting between IS, Kurd Forces in Syria

Fighting raged for a third day Saturday between the Islamic State group and Kurdish forces in Syria after IS attacked a prison housing jihadists, in violence that has claimed over 70 lives, a monitor said.

The assault on the Ghwayran prison in the northern city of Hasakeh is one of IS's most significant since its "caliphate" was declared defeated in Syria nearly three years ago.

"At least 28 members of the Kurdish security forces, five civilians and 45 members of IS have been killed" in the violence, said Rami Abdel Rahman, head of the Syrian Observatory for Human Rights.

IS launched the attack on Thursday night against the prison housing some 3,500 suspected members of the jihadist group, including some of its leaders, said the Observatory.

The jihadists "seized weapons they found" in the detention center, said the Britain-based monitor, which relies on sources inside war-torn Syria for its information.

Hundreds of jihadist inmates had since been recaptured but dozens were still believed to be on the loose, the Observatory said.

The prison was surrounded by Kurdish forces with the support of the international coalition, it added.

"Fighting is taking place on the northern side of the prison," Farhad Shami, spokesman for the Kurdish-dominated Syrian Democratic Forces (SDF), said, calling the situation "exceptional".

The jihadist group said in a statement released on Friday by its Amaq news agency that its attack on the jail aimed to "free the prisoners".

- 'Fat target' -

IS has carried out regular attacks against Kurdish and government targets in Syria since the rump of its once-sprawling proto-state was overrun in March 2019.

Most of their guerrilla attacks have been against military targets and oil installations in remote areas, but the Hasakeh prison break could mark a new phase in the group's resurgence.

It was not immediately clear Friday whether the prison break was part of a centrally coordinated operation -- timed to coincide with an attack on a military base in neighboring Iraq -- or the action of a local IS cell.

Analyst Nicholas Heras of the Newlines Institute in Washington said the jihadist group targeted the prison to bolster its numbers.

The Islamic State group "wants to move beyond being the terrorist and criminal network that it has devolved into, and to do that it needs more fighters," he told AFP.

"Prison breaks represent the best opportunity for ISIS to regain its strength in arms, and Ghwayran prison is a nice fat target for ISIS because its overcrowded," he said, using another acronym for IS.

The prospect of a repeat of the attack remains very real, said Colin Clarke, research director at the New York-based Soufan Center think-tank.

"The SDF needs a comprehensive strategy to deal with this threat," he said.

The Kurdish authorities have long warned they do not have the capacity to hold, let alone put on trial, the thousands of IS fighters captured in years of operations.

According to Kurdish authorities, more than 50 nationalities are represented in a number of Kurdish-run prisons, where more than 12,000 IS suspects are now held.

The war in Syria broke out in 2011 and has since killed close to half a million people and spurred the largest conflict-induced displacement since World War II.
