Istanbul (AP) - On the fourth day of their offensive in northeastern Syria, Turkish troops have invaded the strategically important border town of Ras al-Ain. The Turkish Ministry of Defense reported on Twitter that the site had been conquered. On the other hand, the Syrian Observatory for Human Rights in London said Turkish armed forces and their allies were in Ras al-Ain, but the place was still being fought. The Turkish President Recep Tayyip Erdogan wants to push back with the military offensive of his country, the Kurdish militia YPG in northern Syria to 32 kilometers south of the border.
