Syrian state media, Sana, said the Turkish convoy entered the town of Khan Sheikhoun in Idlib to help armed rebel groups fighting a government advance, denouncing the move as an act of "aggression".
Well, this is true. Syrian army offensive was unexpectedly (for Turkey) fast and successful. Khan Sheikhoun will soon be liberated from pro-turkish "moderate rebels". No wonder that they (Turks) rushed to help their vassals... but something went wrong.
