Northwestern Syria offensive (October–November 2015)

On the 7 October 2015, shortly after the start of the Russian air campaign in Syria, the Syrian government forces and its allies launched a ground offensive against anti-government positions in northwestern Syria, initially in northern Hama Governorate. The primary objective is to seal off the northern Hama border with Idlib and "build a buffer-zone around the city of Khan Sheikhoun".
