Turkish artillery units stationed on the Syrian border started to bomb the positions of YPG, PKK’s Syrian affiliate, on Thursday afternoon following the advances of the terror group towards the northern Syrian town of al-Bab. Their advancement comes despite initial U.S. pledges that they would withdraw from west of the Euphrates Rivers.

Military sources report that Turkish army started heavy artillery shelling against YPG elements following the move of the terror group towards al-Bab, overrunning eight more villages and approaching as close as 9.8 kilometers to the strategically-important town.
