Looks like Turkey's new policy is to create a safe zone in a small section of northern Syria which will protect rebels it backs there and defend an important border crossing from falling into PYD hands. One wave of bombing in Syria was to hit IS supply areas near a rebel command center in that area. Striking PYD & PKK targets appears to be a bigger concern as Erdogan opposes any kind of Syrian autonomous region in northern Syria which is already de facto come into being.
