Syria: Former Islamic State leader caught by SDF, international coalition in Deir Az-Zour province

A former leader of the Islamic State (IS) group has been arrested by Kurdish-led and international coalition forces in Syria's Deir Az-Zour province.

The former senior member of the extremist group was arrested during a security operation in the town of Jadid Bakara conducted with coalition air support, the media office of the Kurdish-led Syrian Democratic Forces (SDF) said in a statement overnight Wednesday.

The detainee was involved in planning attacks and transferring weapons, improvised bombs, ammunition and money to the cells belonging to the extremist group in Deir Az-Zour and Syria's north and east, the SDF said.

On Wednesday night, two SDF members were injured following an attack carried out by gunmen on a motorcycle. The attack, which was claimed by IS, targeted a checkpoint at the entrance to the village of Al-Hariji in northern Deir Ez-Zour.

Overnight Tuesday, US-led coalition forces carried out an airstrike operation with SDF ground support in the village of Al-Sijr. The results of the strike are not known, The New Arab's Arabic sister site Al-Araby Al-Jadeed reported.

Four SDF members were injured on Monday when they were targeted with an explosive device in the south of Hasaka province, an operation IS also claimed responsibility for.

The SDF is loyal to the Autonomous Administration of North and East Syria, a Kurdish-led authority that has broken away from the regime of President Bashar Al-Assad.

While IS has lost all the territory it once controlled in Syria and neighbouring Iraq, it continues to fight a low-level insurgency in both countries.
