Much more to come on this I suspect.
Breaking: Syrian Army looses artillery fire on Turkish forces in south Aleppo, casualties reported
5 February, 2018
BEIRUT, LEBANON (7:53 P.M.) – The Syrian Arab Army or allied paramilitary groups or both have reportedly started shelling the freshly established positions of Turkish forces in the southern countryside of Aleppo province according to both opposition and pro-government sources.
Opposition sources says that Syrian Army and allied Iranian-linked paramilitary groups have unleashed artillery fire onto recently established positions of the Turkish Army in the strategic Al-Eis area of southern Aleppo province.
Pro-government sources report that shelling of Turkish military positions has taken place – even claiming wounded among Turkish ranks – but do not specify whether or not the Syrian Army or allied militias or both are responsible for the attacks.
What is known is that non-Syrian Army pro-government units based opposite the Al-Eis area are mostly Iranian-linked or Iranian (proper) forces.
On a final note, Turkish Army artillery has apparently responded to the attacks with a rocket artillery salvo against government positions around the town of Shugheydilah.
