A SWEEPING deal announced between the Syrian government and the country’s main Kurdish-led force appeared to be falling apart on Monday, just one day after a ceasefire was agreed.

Following new outbreaks of clashes on Monday, the Kurdish-led Syrian Democratic Forces (SDF) issued a statement calling for “all of our youth” to “join the ranks of the resistance.”

Earlier in the day, Syrian government forces and Kurdish fighters clashed around two prisons housing members of the Islamic State (Isis) group in Syria’s north-east.

The Kurdish-led SDF said that several of its fighters have been killed and over a dozen others wounded.

The clashes came as SDF chief commander Mazloum Abdi was said to be in Damascus to discuss a ceasefire deal reached on Sunday that ended days of deadly fighting during which government troops captured wide areas of north-east Syria from Kurdish forces.

The SDF, the main United States-backed force that fought Isis in Syria, controls more than a dozen prisons in the north-east where some 9,000 Isis members have been held for years without trial.

The army said in a statement that some of the Shaddadi Prison detainees in the town of Shaddadeh were able to flee amid the chaos and a curfew has been imposed because of the breakout.

The office of Syrian jihadist interim president Ahmad al-Sharaa reported later on Monday that he had spoken with US President Donald Trump and “affirmed the importance of preserving the unity and independence of Syrian territory” and “the need to guarantee the rights and protection of the Kurdish people,” and continuing the fight against Isis.
