Turkish artillery is pounding suspected Syrian Kurdish positions near a town in northeast Syria as Turkey’s military incursion enters its seventh day.

Axar.az reports citing an AP that journalist on Tuesday reported heavy bombardment of targets in the countryside of Ras al-Ayn, days after Turkey announced that it had captured the border town. Turkish jets also carried out at least one airstrike.

The Syrian Observatory for Human Rights, a war monitor, reported Kurdish fighters had retaken the town.

A Turkish military official denied reports that Turkey had begun an assault on the Kurdish-held town of Manbij, without giving further detail.
