One of ISIS’ top commanders in Syria was probably killed in combat as the extremists sought to stave off an advance by U.S.-backed Syrian forces towards a strategic dam in northern Syria, the Syrian Observatory for Human Rights said Tuesday.

 

The commander known as Abu Jandal al-Kuwaiti was killed as ISIS fighters tried to drive the Syrian Democratic Forces from the village of Jabar captured from the extremists Monday, Observatory Director Rami Abdulrahman said.

 

The ISIS counter attack, launched overnight, failed. The U.S.-backed Syrian Democratic Forces (SDF), including the powerful Kurdish YPG militia, have advanced to within 5 km (3 miles) of the dam, Abdulrahman said.
