Turkish authorities says at least 13 people were killed by a car bomb in the northern Syrian border town of Tal Abyad.
Turkey’s defence ministry said at least 20 others were wounded by the blast.
Turkish troops and Turkey-backed rebels last month took control of Tal Abyad and other border towns from Kurdish forces, after US troops,who were protecting the Kurds pulled out.
According to a UK-based monitoring group, the Syrian Observatory for Human Rights, Pro-Turkey fighters and civilians were among the dead on Saturday.
Turkey’s defence ministry accused a Syrian Kurdish militia group, the People’s Protection Units (YPG), of planting the bomb but no group has claimed responsibility.
