Turkish President Recep Tayyip Erdogan has vowed to press on with an offensive in Syria until his mission to create a “safe zone” is complete.
Turkish forces launched an operation to clear Kurdish fighters from northern Syria last week, after US troops allied to them pulled out of the region.
The Turkish government views one of the main militias as a terrorist group.
Russia has vowed to not let them clash with the Syrian army and the US has appealed for an immediate ceasefire.
Mr Erdogan’s comments, given in a speech in Ankara, come ahead of a visit to Turkey by the US vice-president and secretary of state.
Turkey launched the offensive because they consider the dominant militia in the Syrian Democratic Forces (SDF) an extension of a banned group within Turkey.
The SDF alliance on Sunday announced a deal with the Syrian government for help to repel the Turkish assault.
